The Muslims I know are lovely and normal. They don't cut off my head. They send me christmas cards.
I know a Jewish woman who serves ham for her Christmas dinner and buys everyone Christmas presents --- but at some point I think she actually quit being of the Jewish faith. Muslims who don't bother much with the Koran are usually good enough people but at some point they have become in name only --- which is perfectly fine and healthier for the rest of us.
True, there are some really nice Muslims out there. And I've known many. But it's hard to tell the good ones from the terrorists, though, who don't exactly wear signs on their backs.
