Atheism, which is based on what's known, what's logical, and what can be proved, serves as a conflict to Christians who wish to have America turned into Dark Ages Europe. They don't get how someone can possibly reject their point of view, even though none of it is supported by known facts. Christians, at least the conservative variety, are fond of trying to force, by almost any means necessary, their religion onto everyone, regardless of whether they actually believe it or not, and atheists are just smart enough to ask "why?". This, invariably, upsets them, since they have no real answers, or at least logical ones. And, since it's impossible for them to screw up the country, they blame the atheists. Atheists are the reason why America isn't a theocracy, which is their biggest dream, since we all know the Bible says that the Americans are god's chosen. Atheists and their logic and science, who needs them? Even though, if it weren't for the advancements of science and technology, brought to you by atheists/freethinkers, Christians wouldn't be able to enjoy those things which make their lives easier, but that's just nonsense, really. God provided humans with brains, if you believe in god, and atheists are the only one's who seem capable to use theirs, at least when compared with conservative Christianity, and this upsets them greatly. Why? Because it shows the Bible and their beliefs for what they are, just mythological stories, with no real substance, and absolutely no logic to them whatsoever.
Ok, rant over.
