I'm a member of the Bills Mafia. I have season tickets to one of the most blue collar fanbases in football, and my family has had them for 30 years. I'm surrounded by blue collar middle class white guys over 60 8 Sundays a year, and guess what, everyone I know and who is my friend is a middle class white guy (and all their fathers are over 60).
I still don't hear that shit. Even in Buffalo.
Maybe it's prevalent among your friends.....but guess what: I think that is abhorrent, horrific, etc, etc.
