If we ever got a gay or bisexual Batman, whether in comics or film, is there a way they could do it without pissing people(or at the very least piss off the least amount of people)? I have some ideas.
A) There could be a simple passing mention that Bruce Wayne is indeed LGBT but never making it key to his character.
B) Leaving his orientation completely ambiguous. Hints that he might swing one, hints he may swing the other
C) Skyfall style- Show it, but again don't make it key.
The key would be for them not to make it a key element to his character. Treat his liking of men in the same way they'd treat the fact that he has black hair. It's not important, and it wouldn't change the character, and could get past easily.
