Engage the enemy. Not the keyboard.
Ignore the guy. Being a Nazi is his choice.. and his right in this country. I most wholeheartedly agree.. this guy's an obnoxious twit; and should be ignored or squelched.
However; he's got as much right as the next guy to spout his line of drivel; and it's up to all of us to make sure those rights are not infringed upon... else we run the risk of becoming unwitting representatives of the very same totalitarian system he seems to enjoy.
So.. shoot him down.. tear hiss bellybutton up in the sim... but don't entertain his drivel on the keyboards with a response. If I see him flyin bish; I will gladly escort and direct any knit or rook to his location, and smile when you answer his noise with 20mm.
Public Tolerance.. and a swift punch in the jaw when the law ain't lookin... I love America.
