Ok, i didn't say nazi is a good thing, but if a person's behaviour is like a nazi, in this case what can i call it? I ask. Also, why this blocking warning is unilateral? Look at the scenario please; A is saying to B 'You are a killer'. B is really the killer. Calling B as a killer is a personal attack according to you and bad thing. Ok why are you warning only A? Is B right?
