I wonder how folks would feel if there were Islamic evangelists trying to convert people in the US en masse.

Religious freedom is guaranteed in the U.S. You're allowed to "convert" anyone you want with literature, preaching, etc. which I'm sure you've noticed at the airport, out on the streets of a busy city, or at your front door. The U.S., while being predominantly Christian, allows its citizens to practice any religion they choose. So as long as "conversion" doesn't involve holding a gun to one's head, it's perfectly fine over here. In many countries in that neck of the woods, however, it wouldn't go over quite as well.

That being said, I would hope that those who wish to distribute food and water are giving it out regardless of whether someone listens to their preaching or not. Having the aid be conditioned upon being beseiged with "Yay, Jesus!" chants would be rather unscrupulous. But I doubt that's the case. I think these people will try to make sure the word is spread, but beyond that, I don't think there's any problem with it.

Hey, SOMEONE has to do the aid work. There aren't enough non-religious volunteers to do it, so why not let the Bible-thumpers do it?
