Atheists are irrational because we can't handle the terrible consequences of non-belief? Not only can I "handle" the atheist lifestyle, I'm LIVING it.
As far as rationality is concerned, I'm Mensa-quality, just like Vox.
Belief that atheism leads inevitably to mass murder is ridiculous bigotry. Atheists don't have any worse (or better) record than any religious group that has been in power of a major nation.
Atheists at the individual level have not proved to be any worse citizens than anyone else in this country. To make blanket denigrations that we are "immoral" without evidence is prejudice and bigotry. It would be like accusing all Christians of being irrational because they can't handle the illogic of the existence of a benevolent "God," which drives them inevitably to religious persecution of non-Christians and other so-called deviants. That would be a bigoted, false thing to say.
A poster -- I think it was Hank Kerchief -- broached this point earlier who noted that most atheists do not even declare themselves.
I agree that most atheist do not pose a threat to their neighbors. I did point out to Hank (I think) that those atheists who are outspoken in their belief and who acquired power have a horrific track record.
