I'd be very surprised if there were zero atheists that were anti-abortion.
The idea that American “evangelical Christians” invented opposition to abortion is typical American ignorance and myopia. Various levels of opposition to abortion is the norm across the world—for pretty obvious reasons. The rights-based view of abortion is what’s actually unusual and unique to Christian and post-Christian societies.
Either way, I think if you're going to engage in some American-bashing, you should probably cite some sources to back up your claims.
Well, sure, there were _some_, eg both Hitler and Stalin have delegalised abortion in their countries. But I'm not sure if that's the kind of moral oracle that todays christian fundamentalists would like to remember.
