How do you know what all atheists feel and think? Are you a mind-reader? Or are you just projecting your own hatred onto others?
Where's the bigotry and racism in a lack of belief in gods? Sweden, and other parts of Northern Europe are ruled by non-religious people (not necessarily atheists, though), but we've had no Christian holocaust, so far. The Swedish Church is a strong force for helping the poor, both in Sweden and in third world countries.
Atheists don't believe in Satan or Allah either, silly. You do know that Muslims and Christians worship the same god, basically, right? And, that Satan is in your Bible, so it's more probable that you believe in Satan, than that any atheist (who sees the Bible as just a collection of ancient stories) believes in Satan.
If you think atheists are "nasty people", you'll feel more at home in Iraq or Somalia, than in the Netherlands or Sweden, I'm sure. Go right ahead, for all I care; I'd rather live with the "nasty" people in Sweden (one of the five happiest countries in the world), than with "pleasant" people who orchestrated the Holocaust, Crusades, Pogroms and Witch-hunts.
