I think I've come to the conclusion that a significant amount of people that are against LGBTQ+ are just pissed off that they can't come out because they'll be ostracized by their community or family. Either that or they have religion so far up their ass that they think that if they do this to all LGBTQ+ it somehow makes up for their impure thoughts. And since they can't have it, nobody can. Or it doesn't even exist otherwise they'd be "evil."
"I can't be transgender! Transgender people don't even exist!"
