In my many years as a Witness, I never knew any that used the kind of harsh, insulting language used by You Know. I think he is a very poor reflection on his religion.
Jesus on occasion called his opposers fools and hypocrites and blind guides. No doubt you would rebuke Christ as a poor reflection of his religion for scorching the Pharisees the way he did. Paul once called a man who was trying to turn someone from the truth,the "son of the Devil." The fact is apostates are some of the most vicious slanderers and blasphemers on the planet. But they also are some of the biggest whiners and cry babies when someone turns the tables on them. Fact is, apostates typically wail the loudest when the Scriptures are brought to bear against you. / You Know
