Look, Nazis. Go do your thing somewhere else.
If the Dropkick Murphys see you doing a Nazi salute or any of that crap at their shows, they're not gonna be happy ... and may even kick your ass personally.
So we found out when the Irish rockers were playing a show at Terminal 5 in NYC last week and invited the crowd on stage for a few songs, which is awesome.
Until some skinhead started Nazi saluting to AC/DC's "TNT" ... and singer Ken Casey choke-slammed the loser. Not something you see every day ...
Ken emerged from the melee and shouted into the microphone, in case it were unclear, "Nazis are NOT F***ING WELCOME at a Dropkick Murphys show."
