The JW religion, with its parent company, the WTS, is a cult, but they're not in the same class as Westboro. Today's WTS is WT-lite, compared to the old days. They used to be in-your-face with their doomsday predictions and preaching style. Today they work hard to not bring attention to themselves. They do preach the messages of how God will destroy all that are not affliated with them, but they stop short of picketing funerals and holding up signs that God hates entire groups of people. They save their harshest depictions of Armageddon for members' ears only. And that's to keep them scared, and in line.
The WTS is sneakier than Westboro. They don't wear their beliefs on their sleeve as does Westoboro. Westboro folks are so delusional, they really do believe the shit they shovel. The WTS probably knows that they're doctrines are all shit, so they're just protecting what little empire they have left. Westboro groupies are hardcore, willing to alienate everyone around them to spread their message. JWs are duped sheeple who are too lazy to investigate their own beliefs, and who try hard to not raise suspicions among worldly people, that they are indeed WT cult members.
