The reason I titled this "Today in American Christianity" is because this occurred in America, in a Christian town, as far as I can tell. I am not blaming Christianity wholesale. As was pointed out, this kind of shunning and harassment could occur if you opposed any deeply entrenched tradition. At the same time, pretending that Christianity is just the excuse to further otherwise human behavior; discrimination, shunning, etc, is kind just shutting your eyes, really. The bible commands that homosexuals be killed, stoned and so on. Likewise it mocks disbelievers, encourages morally bankrupt concepts like Jesus forgiving your sins(I'll explain if need will really be). Fear of what's different, like homosexuals, is to be expected in any culture, religious or not, but the concept of guys liking guys being an evil abomination worthy of eternal torment in a burning inferno is something that Christianity chisels into its believers heads, both scripturally, but also societally. I have a hunch that that these people aren't fundamentalists. It's not fundamentalists ganging up on him, it's cultural Christianity. I'm gonna go out on a limb here and say that if these people were not Christian, their knowledge of atheists would not be poisoned by the bible as their culture has been.
All I can say is, thank God(derp) that the law is clear on this subject, and that, in light of that, "he was a dick!" is absolutely irrelevant. Even then, the lawsuit is the best option, because it's obviously the view of these backward hicks that he's trying to destroy 'murica, so might as well come out swinging... heh.
