I fully believe that the user in question is a Nazi. There is no other rational explanation for their behaviour .
There are other explanations, such the one from my comment you replied to. You may not agree with my interpretation, and Seagoon has not posted to clarify the thinking behind their comment. If it becomes clear that a user is a nazi, I'll take appropriate action, as I have done with previous users.
Any space that allows that user is a Nazi bar.
I disagree with your characterization of Seagoon as a nazi, this is categorically not the case.
