Why do Muslims and Christians (not all) make up the most illogical stereotypes?

[ryankirk]

Thing like "Atheists know in their hearts that God exists and are just rebelling" (lolwut?) and
"Homosexuals eat feces" (the smallest percentage. there are weird heterosexuals that do it to) and
"All Christians are caring & loving people" (not meaning to insult the ones who are. i appreciate you for not biting my atheist head off)
