Being gay is not.
Dumbest thing I've ever heard. Yes, some people are genetically predisposed to be gay. So are heterosexuals, alcoholics and serial killers. My best friend, whose dick I rather enjoyed sucking in my younger more experimental days, and brother in-law are gay. They both chose to be gay, and are proud of the choice. My best friends partner is actually straight, as in he's sexually attracted to women. He just enjoys the partership of a male, can't stand women, and likes how a man handles him in bed. Everything is a choice, with the exception of physical traits. Oh, both my best friend and brother in law thought this case was bullshit, as they are libertarians. The people I associate with on a regular basis are almost all gay. Only one or two of them claim that they were "born gay". Meaning they knew they were homosexual at a young age. It's almost always lifestyle and friends that influence sexuality in my experience
Don't lump everyone in a pile. That's where we go wrong when it comes to this stuff. We're all individuals.
