Yea I definitely agree. Hell when this was revealed, I saw at numerous different forums people who were LGBT even saying that the revelation was trash and even just insulting. Are we really gonna call people who are themselves gay homophobic for not liking this?
And one thing that really gets me are people who keep saying that they somehow like him more now that he's gay or that he should get a solo. Those are the worst kinds of "fans" if you ask me because at that point it's showing that they don't really care about the character of the character and what that retroactively means for the 50+ years of history, all they really care about is something as superficial as the sexuality (possibly matching their own). That imo is not a fan and if I were a creator, that would never be the kind of fans that I'd ever want because that's about as far away from genuine appreciation that it gets.
And for Marvel to say that this doesn't change the character, they're full of the utmost of crap. Not only did they retcon his sexuality, they continuously went on and on and on about it as though that was all that there was to the character to them. That now that he's gay, they can just parade him as their A-lister gay character. When what sexuality the character is becomes more important than anything else about the character, your priorities are in the wrong place. You do nothing to assure the fans that nothing is going to change and drive full force that that's all there will be to the character from then on. Iceman's fans have the right to be angered at this and I feel they deserved much better.
