They train JWs in the art of attack and paranoia. Rather than really examining their own religion, they deflect by finding something "worse" in Christendom or other religion. JWs don't even see how they have been twisted in this way.
Oh, and their finely developed moral superiority that is based on NOTHING actually different than any other religions teach or practice. In any case, they don't actually practice it any better, they just brag about it. Its annoying to listen to their cloying self praise.
