I don't think many JWs have good reputations anywhere. We have this local paper with this section called "Blow Off Your Steam" in it, and people write in to complain about things that are bothering them in the neighborhood. Seriously, a couple of times per year, people write in to complain about people coming to their door to preach to them and hand out "religious propaganda." They never mention the name "Jehovah's Witnesses" per se (or the editor takes it out) but we all know that's who they mean. There are hardly any Mormons here, and none have ever come to my door nor to the doors of anyone I know.
I have never heard of them doing a single thing for the community... the only time they make any kind of news at all is when they are in the real estate transactions for selling their Kingdom Halls to libraries, dentist offices, daycare centers. I would say no one has ever heard of them volunteering, donating a thing... they never hold any fundraisers, participate in any charity events, get involved with the community at all. I think we all know that's because they think they're doing everyone more of a favor by spending their time door-knocking. Anything else, to them, is a waste.
I also know that whenever people mention them, the blood issue almost always gets brought up... and people are downright disgusted by it.
