Reveal it via a couple of lines in a comic/short story - “You’re shoving it down my throat!”
Reveal a non-stereotypical character to be LGBT - “It’s forced!” “He isn’t gay!” “It doesn’t fit his character!”
So even when they try and break the mold of what an LGBT can be, that they don’t have to ‘act gay’. Even when they go out of their way to add it in a natural way, by not just saying “OH BY THE WAY I’M GAY.” Even when they reveal it OUTSIDE of the game, it’s just not enough.
The fact is there are people out there that will never be happy how an LGBT character is revealed, it will ALWAYS be done wrongly, it will ALWAYS be supposed virtue signally, it will NEVER just be because, maybe, that character just happened to be LGBT all along.
