I mean, people kind of believe what they want to believe when it comes to fictional characters though, right? And if they decide not to like a character and they aren't necessarily going to try to be logical or look deeper, then they will be stuck in their viewpoint.
Case in point, I really dislike Fantomex. But have I ever read up on or tried to learn more about the character and understand his motivations? Nope. And am I going to? Probably not. I already have enough characters to be invested in and it's easier just to see him as the surface character I dislike. Same goes for Sabretooth. As I know the character, he has been brutal and evil in most of his interactions with the characters I like. But there are plenty of fans of his that don't see him that way because they are deeply invested in what motivates him and how he could change.
So there will always be fans who hate a character for their surface presentations or a specific deed or interaction they remember.
And to that I just shrug, because there's only so much one can do to change a mind that isn't interested in being changed. Some people don't like Gambit, some people don't like Rogue, I might find their reasons nonsensical, but such is life. If they can manage not to be jerks about it, then it's easy enough to agree to disagree. It's the not being jerks about it that becomes problematic on forums. A lot of the tumblr group are pretty done with forums as a result. Which is too bad because we have some great discussions on here and that group has amazing insight to contribute. But I can't blame them either.
But yeah,
I'm not sure what Claremont was trying to do with the Storm kiss. If it was going to factor into some scheme down the line or if he was trying to tell us something about their past? I found it odd. Though when Storm kissed him more recently in Gold when he was feeling down about the nanosentinel debacle that felt more like a friend trying to be kind and lift the spirits of a friend than romantic. Honestly I don't think we'll ever know and don't expect it to be brought up by current writers, which I'm just fine with. I like Gambit and Storm as platonic friends, especially considering he met her while she de-aged to a kid. Though I know some people like that pairing. I'm all about a stable Romy relationship though.
