Every demographic has its wackos, but I don't think I've ever heard of corporal punishment of that extent being endorsed by Jehovah's Witnesses. I heard of a sixteen year old once that was on those steroids that give you big muscles and make you crazy and he slit his girlfriends throat. 'Nuff said.
Here in Arkansas, I've heard of Witnesses doing their rounds in the Ozarks getting run off with a shotgun.
I have seen cases where children were basically disowned by their parents and siblings when they strayed from "The Truth", as Witnesses call it. I see no way in which this could benefit either party. I'm not a religious person in any respect, and I see the witness religion as one loopy coping mechanism among many. At least they don't fight wars in the name of God.
Here is one thing I will say in their favor. From what I have
seen, more Witnesses are ACTIVE in their religion than in many others. It's easy to say, "Yeah, I'm a Christian (Jehovah's Witnesses believe in God and Jesus Christ and consider themselves Christians), I believe in God.", and maybe go to a church service or two. Many Witnesses take time out of their day to go door to door spreading the word of their faith, which they feel is their duty according to the Bible. And believe it or not, it is not a comfortable thing for many to do- especially when you're not used to it and you know that the odds are you will be facing some serious ridicule. They're still people with insecurities, you know. Despite this, they go out and spread their faith.
