Holier-than-thou xian freakos (namely Catholics, Methodists and Baptists) who take their faith so seriously that any conflict with them becomes your death sentence. They will not debate with you over any issue; rather, they will act like a small child who holds their breath until their face turns red and you finally relent, causing them to believe they've won.
Such hot arguments include birth control, civil rights, abortion, sex before marriage, flag-burning, our jackass president, Harry Potter, porn, and in the cases of many innocent guys, dating their adult daughter if you aren't part of their "perfect" religion. Similar in ethics to nazis.
Ironic that such god-fearing citizens are usually the ones who use blasphemous language (ie, "Jesus Christ!") more than anyone else, and advocate killing Planned Parenthood employees and prisoners.
