They scare me. Both Mormons and Jehova's Witnesses. One a few occasions, I've told them (Jehova Witnesses at my door) that I was Jewish or a Satanist. They usually don't know what to say and leave you alone after that. You should try it next time they approach you and end with a "Hail Satan!" and salute.
Hell,
some Southern Baptists, Catholics and Muslims scare me too. Anyone who exhibits religious fervor scare me. I've just had bad experiences with Mormons in particular. All of the ones I've met were mean, phony, and very judgemental. I'm not saying that
all of them are going to be this way.
I once saw two Jehova Witnesses staring at a baby bunny rabbit that had somehow found it's way in the middle of the road. The bunny seemed injured or in distress and they just stood there smiling this creepy smile as they watched the bunny. I thought they wanted to help. You know, at least pick it up and get it out of the road. Being the good, caring Christians they are, they just left the bunny in the middle of the road. So I took off my coat and carried it home. It turns out that it was blind. I took care of it but it died a few days later
