Maybe atheists are less inclined to try and create hell on earth for the unrepentant, but I've seen some really vicious attacks by atheists against a transitioner on an atheist forum, to the extent of comparing her to a guy who claims he's napolean. So I'm not inclined to presume that atheists will necessarily be less hostile towards us than the religious. Who knows, though? Maybe those particular atheists would have been even more hostile if they were religious?
