Oh yeah, I still knee-jerk against Psylocke becoming Asian, learning kung fu and dressing like Elektra, or Thunderbird II going from lean and strong to a bulky 'tank,' or Sam becoming an External, or not, or Bobby becoming Reignfire, or not, or how Wolverine was a shy mouse around Mariko, as if he'd never dated before, and has since been retconned into having, like, fifty kids by forty-something other women. Rogue and Gambit have developed all sorts of amazing powers. Bobby himself has evolved from some guy who threw snowballs at Magneto to some sort of ice god that can create semi-sentient ice elementals, and reform himself, and travel halfway around the world through water.
It's comic books. Who he dates, woman or man or alien or demigod or atlantean or inhuman or space-cloud-in-human-form, is always going to be a minor barely-relevant detail compared to what sort of mutant power he's swinging around.
Or Wolverine, for that matter. Introduced with super-speed and claws that came off with his gloves, in an issue of Hulk, IIRC. And now he's an immortal regenerative person whose claws have gone from being metal implants (seen clearly in Days of Future Past), to a thin metal coating over bone claws. Goodness, I hope he didn't have any fans of the super-speed version, 'cause they must be pissed...
