Many years ago I was at a gun show, and actually witnessed (2) gentlemen with Aryan tattoo's on them talking to and even passing over a carbine to (3) gentlemen of African heritage wearing blue bandanna.... and to coin the adage from Pulp Fiction: They were all just like Fonzy!
Needless to say, that didn't make me feel real comfortable, so I meandered my way away from the table. But there were no signs of attitude from either party.
