I wasn't going to chime in on this but since we're still talking about it I'll throw in my two cents. To me, Gambit is one of the worst choices to make bi-sexual. Gambit is the quintessential Ladies Man. I don't know how you guys feel but I always felt like Gambit was totally in love with women. He's a pure ramantic Romeo type. All his great chemistry comes from female characters. Whether they be partners, love interests, or villains there is definitely a rapport his character naturally has with females. He really doesn't have any interesting or deep connections with any male characters. Outside of having a competitive rapport with other men simply due to their alpha male status's. Not even any real bromances to speak of. But he is fully interested in the ladies. That we know for sure. Making him bi just comes off like bad fan-fiction they pulled out of the blue. Why? Because he is sexual? So because he is sexual they have to make him into both sexes? Is it to make him more with the times? More diverse? To cater to bisexuals? It seems insulting. To everyone. I just don't get it. It makes no sense.
And I am not a fan of how he is depicted sometimes as a "pretty boy". When I think of Gambit I think of a ruggedly handsome type with a smooth style.
