with stuff like this if you are a born Muslim, you should learn at a young age.
Everybody's circumstances are different. Some may not have had a strong Islamic upbringing. Some may have had, but didn't take it all in at the time. Some may actually be young. Some might not be born Muslim. Etc. Whatever the case, it doesn't matter, and isn't our business. The point is somebody is learning now.
When you watch Islamic channels, you also get old ladies, aunties, born Muslim, in their 60's and 70's asking questions about Islamic matters that some might feel are basic. You also get them ringing in to programmes to correct their recitation of the Qur'an. Nobody says to them, why are you asking this, you should know this. Instead, they get praised for asking, and get help and encouragement. What does Islam teach for example, about those who have difficulty reciting Qur'an? See the following hadeeth:
'Aishah :ra: reported the Prophet (ﷺ) as saying:
One who is skilled in the Qur'an is associated with the noble, upright recording angels, and he who falters when he recites the Qur'an and finds it difficult for him will have a double reward. (Sunan Abi Dawud)

'Aishah :ra: reported:
The Messenger of Allah (ﷺ) said, "The one who is proficient in the recitation of the Qur'an will be with the honourable and obedient scribes (angels) and he who recites the Qur'an and finds it difficult to recite, doing his best to recite it in the best way possible, will have a double reward."
[Al-Bukhari and Muslim].

Allah appreciates the efforts of people who are trying to learn and doing their best, and has mercy on them, and the above hadeeths are an encouragement and reassurance, yet what do humans do instead?
no wonder Muslims are messed up.
I don't think that's the reason. I can think of another reason though, that can strike at the heart of brotherhood.
