Just because he writes a book about it, or even preaches it in his sermons, I don't think he can be held liable for what his "followers" actually do with their kids.
Wouldn't it be incitement to violence? Because, you know, he's telling people to be violent?
Incitement to violence laws don't really exist in the USA. Unfortunately. We'd have Glenn Beck locked up for several life sentences, if we did.
Well....we'll propose those laws! Petition for then. Injustice? Change the law. Simple. Remember, there is THE LAW OF KARMA! The Pearls will lose, they will. Same for Westboro. Good will win eventually. Don't believe the lie of "The Karma Houdini". How do you know The Zodiac Killer, Torso Killer & Elizabeth Short's killer didn't get brutally murdered, die from an agonizing illness, get arrested for something else & croaked in the Can (or executed) or get mangled in a car wreck or plane crash?
Sure, some evil people may be an exception but for the most part, bad guys get SOME sort of last desserts.
Being one who who acknowledges the concept of an afterlife, the "Karma Houdinis" get the big payback in the next life (a purgatorial hellish existence or a very crappy reincarnation). You don't have to believe this, of course.
The best way to make things right is to fight for it. Sitting around and bellyaching about the Pearls, Hezbollah House, The Phelps Hate Cult, etc. is not gonna change things! You GOTTA CHANGE THE LAWS, thus...NO MORE LOOPHOLES!!!!
