Hitler is a name. Just because one person a while ago who was a pretty horrible person was called Hitler does not mean that there is something wrong with simply the name. Anyone can be called Hitler, and there is really nothing to say that it is referring to Adolf Hitler who started World War II.
You kicked this guy about 3-5 times for his name, even after Kitty kept on telling you not to because she was going to ask Clarky/Max about it because Clarky (higher ranked than Para, may I add) had said before that it was fine. I would not be surprised if sexually retracted hitler made a report against you for it, and if I were them then I definitely would.
