A Christian responds that Hitler was unilaterally responsible for 20 million deaths, conveniently, you might say religiously, cleansing of all responsibility and freeing from attributions of causality those millions of nominally Christian Germans who held the rifles and ran the trains and supported the supposedly evilest guy ever as long as they could find employment and/or as long as the evil one gave them outlets for their hate and/or as long as they were winning on the battlefield. So chalk up 20 million murders to the atheist team. Those atheist bastards.

if I may interrupt, dammit, the humans have been organizedly killing each other for as long as they've deserved to be called human and they've been giving their reasons all sorts of names, fighting under all sorts of banners and flags, fighting for various tribes and ethnicities and nations, sacrificing to all sorts of gods, going to differently shaped churches and now I don't really think it matters what name you give your sociopathy, it's pretty clear that Christianity and Islam and Dawkinsian atheism and Obamaism and so on are mostly just along for the ride, like Peyton Manning's hair.
