Spending several decades of my life hearing right-wing politicians and voters tell me that my "lifestyle choice" is bad, that I'm a degenerate who is ruining the country, that I don't deserve equal rights, that I deserve to be executed, and so so many other repulsive things like that definitely pushed me towards the other direction, politically.

Truthfully though, even if I weren't a part of the LGBT+ population, all the other ridiculous stuff would have been more than enough on its own to turn me off to right-wing politics.

Realistically, I think it's the authoritarian core of it mixed with the anti-intellectual principles that I always found off-putting. Although I never would have guessed we'd end up where we are in the USA back when I was a kid, this all honestly makes sense.
