I used to tend bar in Milwaukee, and there is nothing that triggers self-conscious weiners more than beer. I cannot tell you how many arguments began with some dude – always unsolicited/unprovoked, mind you – feeling compelled to judge and "educate" other guys about the beer they're drinking (or not drinking).
"You drink that piss, you pussy?" and it goes downhill from there.
No one cares. Drink what you like and shut up.
