There are quite a lot of em. You won't see them with rainbow flags, they aren't into any of that, or the Pride mess parades, or clubs/bars. They are kind of just regular dudes, who happen to be gay. One of the veterans I sit with, just retired from the military he was a SEAL, masculine as hell etc, he's gay. People don't believe him if they find out, and he's got girls chasing after him even if they do find out lol.He doesn't hate himself or anything, his family knows and doesn't care... These guys just don't see their sexuality as something important or to broadcast.
I've also noticed, politically these guys are either more libertarian (socially- live and let life, all good with you, unless you are hurting someone, stealing from someone, forcing something on someone, killing someone, or disrespecting the constitution/freedom etc), but typically vote Republican, not blindly though because they tend to despise both parties though the other more so lol.
