Hold on a second, we need to go over a few things. While it is true that Atheism cannot really stop or even promote atrocities, having no real enforceable intrinsic morality, it isn't quite the same as religions. Religions do not exist separate from their holy texts, so carry ideological baggage and moral baggage, at times the baggage is from centuries ago. While some religious people will be able to separate the baggage from the religion, some quite literally adopt that baggage as if it were from on high, which is why there are some preachers even today that support the stoning of homosexuals. So, no. While no worldview may actually have a monopoly on morality, there is one that claims to have that monopoly, and that does make quite a startling difference.

Is it always bad? No, I don't think anyone has ever met a violently militant Jainist, nor do I think it even possible. But many religions do have far less healthy moral examples imbedded in their texts, and that needs to be recognized as well. Atheism, at its very basic core, has no required beliefs about morality, while religions are often fully-stocked with such baggage. I find this often has both positive and negative effects. It isn't very regular for me to see the more modern protestant sects taking hardline stances on things like birth control or homosexuality, so it seems more emphasis was placed on these in the catholic tradition, to the point that it was only recently that they have changed their stance on protection in aids-riddled Africa.

I think that religion can provide much motivation that atheism can't, both good and bad. It is a mixed bag, and pointing out the bad and pushing against it is only bigoted if you consider constructive criticism bigoted. We should push back against people that condone violence, same with those faith healers that scam money off the poor and sick, and so should you. The fact is, often we atheists are the only ones really voicing our opposition, and silence from religious moderates is nearly deafening.

If you want us to change our opinion of you, give us a reason to. I have routinely destroyed other atheists publicly, here and elsewhere, when they said something I disagreed with about the religious. I called another atheist a nazi for talking about putting Christians in reeducation camps, and so did other atheists en mass. Whereas when Christians say similar things about atheists, those that bother to comment agree, and those that disagree don't even bother to condemn it. We only ever hear from the vocal minority of your side that believes we are either satanists, or self-denying theists, and attack us with verses out of a book written by people so ignorant they thought striped sticks would encourage striped sheep.

So, while we are prejudiced, it isn't without cause. Every other group to ever fight against prejudices had to do so by destroying them through action, and so have atheists for the most part. Meanwhile, it would seem religious people seem to think they should be immune to our prejudice merely because they mysteriously somehow deserve the benefit of the doubt. No, if they want people to change their perception of them, they will have to work for it just like everyone else, ever.

Welcome to reality, have a nice day.
