What stupid take is this? Being a lesbian isn't a race. Just like being gay or other labels. A hot, ugly, healthy, ill, rich, poor can be those. Don't let social media influence you. Those people that are loud, are the minority, not the regular people.
As for fantasy, anyone can be the hero or the main focus. There is no criteria to it. It all depends on who is narrating it. The best Jesus interpretation in film industry is made by a an atheist.
The issue with those topic, is that you are removing personalities, which is why you end up with bland interpretation. The person in the story need to be relatable. Being a lesbian doesn't mean you don't struggle with daily lives. These small moments make us relate to the character in some way or another.
p.s I worked with lesbians. Both hot and meh ones.
