My favorite part of this shit is not understanding that your entire life has been filled to the brim with straight, white "propaganda". And now these people who barely had any open role models to choose from are trying to join the public eye, and the homophobes lose their damn minds. And no you don't need to be all of those adjectives, there's a lot of homophobia and tribalism in non white communities.
And the worst is, most will say they're perfectly fine with "the gays", maybe even have a friend or family member who is, but you're just saying you don't want them to have the same priveleges as you. Same with racist shit like freaking out about gender or race changes to movie characters, or simply female/POC/LGBTQ characters existing at all.
It's always "shoved in their face" instead of seen as it is, being exactly the same as having straight, white, male heroes.
Sincerely, straight, white, protestant upbringing who understands that my entire society was handing me heroes, role models, protagonists, etc that I could identify with and maybe other people deserve the same damn thing
Edit: and on the "it's probably not homophobia, just being dense" comments from earlier, reminder that homophobia doesn't mean militant anti gay actions, just like racism isn't confined to white hoods and cross burning. Holding hands with your wife, and then seeing a gay couple holding hands and thinking that they shouldn't flaunt it... That's homophobia. Watching a million movies with straight romance, and seeing a trailer for one gay movie and thinking, "LGBTQ propaganda"... That's homophobia
