1) Atheism is a religion
There are different kinds of atheism, some compatible some incompatible with each other. A coherent definition means "no God"...I guess there may technically be some wiggle room for spirituality religion in there.
I've heard it stated that in America there is no such thing as an atheist. I think that's not true, what is meant is that they don't believe on a concept of "God" in a way most people who traditionally do, do. Americans are happy to be Buddhists, vegans, pacifists, nationalists, racists, or whatever... but not Catholics or "fundamentalist". Very moral, and very spiritual.
It may be stated that atheism is a direct response to pagan, Aristotelian/Platonic, Muslim, Jewish, Christian, and Zoroastrian conceptions of God. Or it is at least a critique of certain aspects that keep cropping up within them.
"Fundamentalism" and cultural disgust may play a part in the atheists knowledge of "religion", but probably not a very large one. If anything they play the part of one party making fun of, or using as a straw man/ boogey man the inevitable fringe elements of another party. Clearing up "fundamentalist" myths is a waste of time usually. Heck, the word itself is probably dangerously vacuous.
2) Atheists have no morality of their own, and just steal Christian morality
Some of this could be true, and much of it is admitted by atheists. Once again it depends on the atheist. Marx and Hume are incompatible, but both would admit that xtianity was part of the moral makeup and appropriate that in their thought in different (incompatible) ways. In his own way, Nietzsche admitted it too.
An atheist could think that God actually contradicts or leads to catastrophic consequences of any coherent moral sentiment that can be rationalized, experienced, or talked about. In this way an atheist can be disgusted (as they usually are) with various ethics of various religions.
Frankly I don't think focusing on morals is a great thing. Atheists, Americans, hard core secular political ideologues or whomever love morality and the smugness it gives weight their cause just as much as anyone.
3) They're only atheists because they want to continue their perverted practices
Lots of people will stick to any "ideal" to confirm their whims. This says nothing for or against anything. This is a psychologism
4) Atheists are just people who are angry at God
I think that means they are not atheists by definition. An atheist does need to have some concept of God though. Once again though, they can be disgusted by the consequence of belief.
5) Atheists only attack Christians, because Christianity is the one true religion
Most people hate Islam. Secular Jews can be pretty hard on religious Jews. Classical paganism is dead, so there is nothing to attack. I'm not too sure if there is any debate in Japan or India on paganism vs atheism, that's not my thing. If not it does less one to suspect that atheism is more of a "western" phenomenon...which is interesting (this also does not contradict many atheists, such as Nietzsche).
6) Atheism logically leads to nihilism, so they should just kill themselves
This is an is /ought fallacy...the concepts if of atheism and nihilism though, as I've been stating, are too broad anyway. So this makes the "atheists ought kill themselves conclusion even more shaky. I get a lot of self professed atheists (maybe Camus and Sartre) say that killing yourself is cool...but they were "existentialist", and hence a bit of a joke.
8 ) Atheists are usually adult men living in the basement of their parents
No. Interesting someone would signal out this group though. It's like saying atheists are "not fit enough" to be on planet earth, they are "beta males", the most "reactionary" class of all.
Sounds like a strange, smug, and triumphalistic , social Darwinist claim.
9) Atheists love evolution because it gives them an excuse to act like an animal
No
10) Atheists are blind and refuse to see the overwhelming evidence for the existence of God
I have no clue what this is about. If you're using the word evidence (an empirical term, as opposed to the inferior term "proof"), the word already implies subjective interpretation and a bit of humility between two people. It's hard to tell me what the opposition really does see.
11) Atheism has caused more death in the world than any other religion
This is probably useless categorical thinking. It's probably reactionary to. Using opposing narratives and categories to defend one's own position. That seems odd.
Besides how much of this is about abstract terms (religion vs atheism), and utilitarian numbers? That seems a bit macabre.
What atheist or what Christian killed which person? Why? That's more important. I'm half tempted to call that line if reason vulgar philistinism.
"One man dead is a tragedy, a million is a statistic" , Orthodox seminarian Joseph Stalin...a philistine if there ever was one.
12) Atheism arose due to a warped western Christian theology
I said earlier this may be a more western phenomenon. It's worth looking into. I'm.not too sure of that's right, but there is merit to this line of thought.
