Here's a factor, so to speak, that might blow the rails out from under this whole thing: regardless of how it was retconned later to justify it, SCOTT ABANDONED MADELYNE PRYOR THE INSTANT JEAN POPPED UP. Where's the outrage over that, and did Jean care about MP?
Frankly, I'd find that a lot more repulsive, and creepy because it only underlines his weird fixation of Jean not really being love. He only liked MP because she looked like Jean. I'd say that was a deeper issue.(That was also around the time I dropped X-Men and all Marvel for a while, when Jean returned)
