However...
Mormons in the US in the 20th and 21st century have generally been politically conservative and good citizens.
They are no better or no worse than any other groups.
What they DO have is very good PR at keeping the BAD things covered over.
What is the breakdown on voting?
Catholics vote more Democrat. Should we condemn Catholicism for that?
I think the Mormon values can change. That is a concern.
For example, I think they will be OK with same sex marriage, for two reasons.
1) to get the gay market. If SSM is ok and legal, they can get a lot of gays to join.
2). SSM makes polygamy ok as well and a legal return could take place.
