@ThisMet you don't see straight people demanding representation because they already have it. In every single form they can get it. LGBTQ+ representation is much harder to come by, and even when we do, it's usually catered towards straight people. The most common examples being over-sexualization and putting the LGBTQ person in the wrong. Like the movie Love Simon, where HE was wrong for not coming out sooner, or this manga, where Rei is a manipulative perv.
I don't condone attacking the creator for not having it, but doing it wrong is damaging to the image of LGBTQ+. One of the biggest ways homophobes have turned people off supporting gay rights is by representing gay men as pedophiles.
Both sides are extremely loud on whether or not something gets representation. Just look at the responses to there being a non-binary option in Call of Duty. The difference is that homophobia is normalized, whereas demanding for rights and representation is not. It's a easier to put LGBTQ+ people in the spotlight for being irrational. Again, attacking a creator is never good, but it's not as if we're the main perpetrators.
