> These people aren't any more racist or sexist or whatever than anyone else. They're just willing to crack jokes about a hell of a lot of stuff that would make most white collar employees cringe.

I wouldn't cringe if I heard off-color jokes at an auto repair garage.

I think I'd call the police if I saw a bunch of dipshits sitting around a workstation, targeting random women from the other room with facial recognition software to share degrading posts about them being receptacles for their own sexual gratification.

Aside from TV sitcoms and online forum caricatures, I haven't a clue what that kind of sociopathy has to do with blue collar workers.
