Off the top of my head, SpongeBob SquarePants, Danny Phantom, Fairly Oddparents, The Big Bang Theory and It's Always Sunny in Philadelphia all have jokes, if not the main plot point of the episode, that are just mocking the existence of LGBTQ people.
The trans Athelete things is really really bad but the garrison one really pisses me off bc they obviously went out of their way to have garrison say:
transphobic bs
“so I’m just a man with a tit job and mutilated penis” and the doctor respond “yup”
