I disagree, I’ve never seen an atheist lobbying about the evils of Buddhism. They focus on Islam and Christianity. Islam because it inspires terrorism, and contributes to the oppression of women and gays. Christianity because of the few Christian politicians who try to incorporate their religion into politics. Tennessee tried to get the Bible to be the official state book, but luckily the governor vetoed it. That’s the kind of thing that atheists fight against.
My problem with a lot of American atheist activists (I can’t speak for ender) is that they fail to see the obvious contrast between the problems we’re seeing within Islam relative to Christianity. As scary as Tennessee making the Bible the official state book is, it pales in comparison to your previous sentence. That’s not to say that they don’t have a point on that issue, but a lot of atheists not only ignore the problems within Islam, but actively defend Islam. That’s what blows my mind.
