I've had close friends who were attacked for walking down the street in their own neighborhoods. Anti-gay violence is a real threat.
Does anybody know Folkies who even talk about beating up gays? I suppose that's a rhetorical question, because I think folkies are more interested in music, as I am, than enforcing societal norms. Still, I'm curious.
As to the perception that gay men aren't participating in folk music, maybe it's just that the gay men who are there don't look and act like the ones on TV and in movies?
