Agreed. And there's nothing wrong with that. There's a big difference between playing a gay character and derailing the entire campaign because you choose to lead a gay rights movement while the world is being overrun by the demon king's hordes.
I don't care about the former and have done so myself, but I'll boot you from my table for the later. Not because I'm against gay rights, but because that's not the kind of story I'm interested in DMing and you're free to find a DM who's interested in this storyline, but you won't take my campaign and players hostage for your narcissistic urge for self-promotion!
