Hold on- what if a character has been gay for a long time and been repressing it, even to themself? Trying hard to be who they thought they were expected to be? Would anyone -COULD anyone possibly object to someone coming out? I know people do object (everyone I knew tossed me out of their lives when I came out as bisexual AND transgendered, but that was like 16 years ago and times have -hopefully- changed). Can we get past calling it a gimmick if someone, be they real or fictional, reveals something about themselves that you are totally unaware of?
No because a majority of the time none of these characters showed that they were in the closet at all. I find it hard to believe that half of the characters that are gay are gay just because they're gay or gay because they're trying to appeal to a targeted audience on purpose or forcing it. There's gay heroes yeah..But don't go changing characters who were straight before into gays. That I have a extremely large problem with because it breaks something that should be incredibly important with a character...Continuity. If they want a gay character so bad then make a new one since that's the thing about characters or groups like the lantern corps..There's not a single defining individual. Like with Spider-man there's been multiple people who've had the spider-man mantle..They could easily make a new one and have it be gay. Also not Cats people don't need to get over it..They're entitled to their opinion and are allowed to voice it. If you don't like it then it's you who needs to get over it
