Theravada Monks

In my reading I noticed that the Theravada Monks beg for food and the people that donate to them, do it willfully and generously. The lay people (the common folk) of the town believe that they receive beneficial karma in return by donating them food to eat. All in all, it is seen as a win win situation.

Why can't we have that kind of generosity here in America? We see preachers go around, like the Jehovah's Witness and people resent them. They pretty much turn away their presence instead of invite them into their homes. I think that it is the way that the preachers and evangelists go about spreading the message. Unlike the Theravada Monks, these preachers for the most part to most people do not share the same gentleness and wisdom. A lot of people just see another old preacher from the south forcing their religious ways upon them. I also think this has a lot to do with the fact that America allows free religion. Not everyone has to be Christian or accept it, but I still think our views of the religious role models here in America dim in comparison to the Theravada Monks in Asia nevertheless.
