Wow, when I saw this I had to put it up on my blog. I think it is pretty bad when non-LDS critics of the Mormon faith have to sink this low. Not only is it unchristian, but very saddening to see what bigotry will lead people to say.
The sign in no way makes me want to be a part of the authors religion or viewpoint. If they can say something as outrageous as this about Mormons, what other outrageous views do they hold?
