Honestly, when people talk about shoehorning LGBT characters, I usually think about what companies like Disney, and how they treat their gay characters like it's a huge spectacle and the LGBT community must support them because they love gays, and then like, the character gets 2 lines in a scene that doesn't do anything for the movie. It's really jarring, and you can tell they only did it because of money and money alone. Like, look at what Paranorman did compared to what Disney does.
I mean, it's annoying when a movie has like one black character in an all white cast, but then he speaks in the most stereotypical way like the writers never seen a black person in their entire life.
But I am straight, so maybe I shouldn't speak on this?
