Childhood-Mormoner here
Anyone willing to TL;DR what exactly JS and others did that was so horrible?
Growing up, I'd often hear the persecution of The Saints likened to the persecution Jesus suffered, which was supposed to be a sign of its truthfulness. I'd hear stories about innocent people being tarred and feathered, or jailed, or, eventually murdered.
Interesting to hear the other side of the story, all these years later.
Also, what's with the absolute Mormon-hate? I mean, I can think of (at least) two other religions that are far worse, and have a lot more followers. They're fairly benign, as far as religious extremists go, especially once you're out of the wacko midwest.
