Here in the U.S., there’s a very strong anti-Moslem sentiment from a large segment of the population. Don’t bother denying it in the comments, I live here and I know.
Most of those who fear or mistrust followers of Islam have an image of the “typical” Moslem being a terrorist, ready to die with assurances that beautiful virgins await him in heaven, if only he can send some infidels to hell when the bomb goes off.
