Wow. I have never heard of anything like that!
I can understand a little joking around, but damn, that takes the cake (and apparently not done in humour, unless it was one sided only...which then ruins the fun). I believe there should be some sense of honour in claiming an affiliation, regardless of what affiliation that is. If you wish to tie yourself to it, you should be proud of it, and not prattle on like a retard. I for one am always down for good discussions regarding history, good, bad or indifferent. I don't think I could have done much more besides hang my head and laugh at the guy. Pointing a weapon is NEVER ok, and is a threat as far as I am concerned.
