Sure there seem to be a few similarities, But a lot of them are a "stretch" and there's far more differences opposed to similarities.
To begin, lets take a look at the history of Catholicism how it was formed. and that history begins with Jesus himself (p.b.u.h.). Jesus was not a mythical figure. Whether you believe he was a prophet, or a god, or a common man. It's hard to deny his existence since he was even mentioned in independent scriptures (The ancient Roman writer Tacitus mentions him, he is also mentioned in an ancient Jewish book by Flavius Josephus.)
However there was practically nothing written down about the life of Jesus (p.b.u.h.). Only years later, people start to write the gospels. And those have been transformed over time a lot of times to such an extend that they become unreliable.
Then there's the freemasons. As Christianity came to Egypt, a small sect was created that had both Christian and ancient Egyptian concepts combined. This sect was first allowed in Christianity but in the dark ages when Christianity started with it’s crusade the sect was labelled heretic and was persecuted. The sect had to flee underground, it is the beginning of the freemasons. But from this underground position they didn't just sit and tell each other stories. They seized power by placing members in certain positions throughout history. These many influential people throughout history that were a member of this sect placed references to this sect in honour of it. The dollar bill, the obelisk in Washington, the pyramid in front of the Louvre in France, the obelisk a couple meters away from it. All referring to their ancient Egyptian heritage.
Now I think that since the bible has been altered so much, and since the freemasons mixed Catholicism with the ancient Egyptian culture that it is more likely for the fake similarities to have been added afterwards into the factual stories about prophet Jesus (pbuh); rather then one story being a knock off of the other altogether.
This being said, lets look at the similarities in detail. I’ll try providing links as I go along. But obviously I’m unable to provide a link that disputes wild claim since obviously no credible source even mentions those. So in the cases of missing source, I challenge you to bring me source that the wild claim IS true, or at least based on something rather then lies
First your own source states (just below the table with comparisons):
Reactions of Egyptologists:
Ward Gasque, a volunteer book reviewer for Amazon.com surveyed twenty contemporary Egyptologists. He asked them about the origins of Jesus' name, the relationship between Horus and Jesus, whether both experienced a virgin birth, and whether the Egyptian religion considered Hourus to be an incarnation of God.
Ten responded, They agreed:
No similarity in name
Jesus' name is a Greek form of a very common Semitic name Jeshu'a, which is normally translated into English as Joshua.
You don’t have to trust your own source for that, here’s an alternative source:
http://www.christianorigins.com/etymology.html
No similarity in virgin birth, 12 disciples, reincarnation of god
There is no evidence that Horus was born of a virgin, that he had twelve disciples, or that he was considered incarnation of God.
Again don’t trust your own source, I’ll bring some of these up further on.
No similarity in birth date Jesus was not born on 25 dec. The actual birthday is unknown as far as I know. When Catholics concurred northern Europe; in order to convert the Celtics they would have to give up there holiday “Yule” which was a festivity to celebrate the shortest day of the year (latest dawn and earliest dusk). So the Catholics cooked up a birthday celebration of Jesus (p.b.u.h.) to compensate. The similarities between the Celtic belief and the Egyptian was not because one influenced the other, but rather because they both based their religion on the course of the sun.

No similarity in mother’s name
The mother of Jesus was named Mary/Mayram, but contradictory to this table the mother of Horus was actually Isis rather then Meri. Horus emerged from a three grown out of his fathers’ coffin. Isis is considered mother later on as the myth evolves. An alternative birthstory then originated stating that Isis extracted semen from her late husband to empragnate herself. There’s no divine intervention or incarnation. Horus was the physical son of Osiris. Note that Osiris also wasn’t the chief god but a son of Geb, as was Isis a daughter of Geb. And even if there were a similarity here. Jesus never claimed to be the physical son of god. In the bible the children of god is frequently used to refer to pious people as it was custom in the Jewish tradition. The concept of Jesus being part of the trinity was brought up much later from an interpretation of on of the Gospels (Johns If I’m not mistaken).

No similarity in between Joseph and Seb
Seb is a bad transliteration of Geb. And he was not the foster parent of Horus but his grandfather. The father of Osiris and Isis.
http://en.wikipedia.org/wiki/Geb
No similarity in birth location
We don’t know where Jesus was born. The story about the stable/cave is debated. But Horus was born from a tree that grew out of Osiris coffin.

No similar annunciation
The ancient Egyptians didn’t even believe in angels. And Isis impregnated herself with the semen she extracted from her late husband/brother. So why would she need an angel announcing Horus’ birth?
http://en.wikipedia.org/wiki/Legend_of_Osiris_and_Isis
No similarity between the star Sirius and the star in the bible showing Jesus (pbuh) birth
Sirius was a deity in the Egyptian mythology called sopdeth in the older mythology which later on assimilated with Isis, Horus’ mother. Whether or not there was a star pronouncing Jesus (pbuh) birth is debated
http://en.wikipedia.org/wiki/Sopdet
No similarity with shepherds
As far as I know there were no Sheppard witnessing Horus birth. Whether or not there were shepherds witnessing Jesus birth is debated. Wild claim.
No similarities between three kings, and three deities visiting after birth
There weren’t 3 deitys but only 2. Isis herself was the third one.

No similar threat
Herut does not appear in ancient Egyptian mythology. The only adversary of Horus was Seth. Wild claim
http://en.wikipedia.org/wiki/Horus
No similarities between rite of passage
There is no similarity between the bar witsha ( I don’t even know If Jesus had one) and the recovery of Horus’ eye. Horus’ eye, damaged after battling with Seth actually never recovered!.
http://en.wikipedia.org/wiki/Horus
No similarity in the break of history in their lifes
Apart from the few events described in mythology, Horus whole life is a big gap. So it’s not like a 12 to 30 year gap, but rather only a few events in his (eternal) life known.
http://en.wikipedia.org/wiki/Horus
No similarities between baptism in the Eridanus/Jordan river
Horus wasn’t even baptised since it was not a custom. Eridanus is not even a river. It’s a constellation wich according to Greek mythology symbolises a river. Anubis was not a baptiser but a different Deity. He is also a son of Osiris, but the two deitys never met. Horus replaced Annubis as the myth evolved. Actually the erason Horus was considered son of Osiris was because he was he replaced Annubis in the mythology.
http://en.wikipedia.org/wiki/Anubis
http://en.wikipedia.org/wiki/Osiris
No similar temptation
Horus wasn’t tempted by Seth, he was attacked physically, they fought. And hours won the battle winning the reign over Egypt.
http://en.wikipedia.org/wiki/Horus
No similar activities
Jesus (pbuh) stilled the sea in a singular event to save people from drowning according to the bible. Horus didn’t still the Nile, in stead Horus constantly made sure that the Nile flooded to fertilise the land. Horus didn’t cast demons out possessing humans, he fought physical demons. I’ve found no case of Horus restoring the blind, in fact he could not even heal his own eye.
No similar raising of death
Horus did not raise his father out of the grave. Isis did that prior to Horus birth. There seem to be some claims about an annual festivity in which worshippers enacted the resurrection of Osiris but he never actually got resurrected, and I doubt the source.
No Simular death
Horus was a living deity, no crucifixion, no thieves with similar destiny, no Burial, no afterlife, no resurrection. Those are all wild claims.
No similar nature
Horus was not half man but born only by deity’s. Horus although good in nature was not considered the savior of mankind, he was not titled the anointed or KRST, he is not commonly portrayed as child held by his mother. He is not associated with pices. He was a deity with the head of an eagle. He did not have similar title’s such as the lamb of God or the savior. Those are all wild claims
No similar preaching
Horus was not a preaching God. He did not have scriptures.. Those citations are inventions. There are no books or gospels. Only drawings on walls which leave a lot of room for interpretation. The reason The myths evolved so much was because they were not written down. When they wanted details about religion they went to the pharaoh who was spokesmen for the Gods and he had different political agenda’s rather then playing Shepard an feeding the hungry. And as long as the Nile kept flooding, it was believed that the Gods were happy with the pharaoh and thus the people trusted the pharaoh as spokesmen.
It seems the further down on the list we go, the wilder the claims. I guess that the y expect that by here you’re either tired of looking it up or convinced by their lies.
