Fox news does all of those things....and they thrive!
No but really. In the end people shun their family because they are taught that is what God wants them to do. It isn't a crime, and isn't something that can be sued over. We have been down that road before. It would only feed into the persecution complex and fulfillment of the "doing away with religion" thing. JW's will exist, and varying degrees of success, and are trying to re-write their history.
I don't think we are at a tipping point. Not at all.
