Most atheists, in my experience, do not disbelieve in God simply because they cannot see Him, ProfessorSunday, although with any number of them it really is just a slightly more complex version of exactly the same fallacy: they disbelieve in a thing outside the nature, purpose, and scope of science because there is no scientific evidence for Him. The reasoning, therefore, is that X does not exist because something which by definition could never confirm or disconfirm it does not confirm it. Comparable to disbelieving in the Loch Ness Monster because you cannot find it anywhere in Lake Erie.
This is a pretty fair assessment, with the minor correction that most atheists actually don't believe against as much as they fail to believe. It is only a rare few who will say they are sure there is no God. Most of us simply fail to see any evidence or reason to believe that there is one, as you noted above. We don't believe in God(s) for the same reason you don't believe in leprechauns, space aliens, or the loch ness monster. We start without belief and see no reason to believe. Even though there are stories about all of these things we have no evidence and faith (believing because you want to) isn't enough for us. I'd also point out that there are plenty of Gods you also do not believe in (Zeus, Odin, etc) , for similar reasons.
Different people, ProfessorSunday, have different reasons for believing in atheism
Atheism isn't something to believe in. It is a lack of a belief in something. If atheism is a religious belief then being bald is a hair colour.

You have that exactly backwards. People are not born with an anti-religious mindset. This mindset (which I agree many atheists have) comes from being an atheist and then observing religious belief. It doesn't happen to all atheists. There are plenty of atheists who are not anti-religious. There is even a good number of atheists who wish they could believe.
In the best cases the atheist is simply led astray by the illusory sophistry of atheistic argumentation, which has a weird way of appearing rational at first glance but being more and more obviously the more and more you see of it and think about it a farrago of questions masquerading as arguments
Atheist arguments are reactive, not proactive. Atheists would not recognize themselves as such or speak of atheism were it not for theism, just as non-smokers would not recognize themselves as such or speak of smoking if it were not for tobacco.
(some of which, like “If God created everything then what created God?” sound superficially like clever comebacks but are in fact really just evasions of the main issue)
Do you understand why this question gets asked? The speaker is not really wondering who made God. The speaker is making the point that complexity does not necessitate something having been created. This is an example of the reactive nature of atheist arguments/debunking. The atheist would not be asking this question if the theist did not first try to argue that since the world is so complex then it must require a creator (the watch maker argument)
arguments against specific religions or religious conceptions of God’s nature masquerading as arguments against the existence of any kind of God
Yes atheists do engage in this too often. Mostly because they have only been exposed to particular conceptions of Gods. It is rare in the west, for example, that we would argue against chi or tao but we do often lump these religions in after taking on Christianity, Judaism or Islam.
I would note that theists play the same game though. I often see people make arguments like the watchmaker one and then claim to have proven their particular conception of God, when really even if the watchmaker argument held, it would only prove a creation force - which could be just about anything.
