That's not really the same. Lightning didn't have hundred of comics featuring him attracted to women.
And even in his few apparitions after being outed, he was able to utter more than 3 sentences before reminding the readers how gay he was.
For me, Iceman had been a boring character for years. Every unimaginative writers were going for the same gimmick: "hey look how strong he is when he unleashes his full potential, I bet the other writers before me didn't think about that!". He just traded one gimmick for another, but he is still boring. Except he now has hundreds of fans suddenly popping out of the wood, either to love him for being gay, or to complain that he has been ruined forever.
