And that's what I mean by comic book logic. "Oh, he got his powers from an exploding toilet. That's okay, then. Long as he wasn't born with them I'll let him save my daughter from that fire."
It doesn't really make sense. But Marvel wants the mutants to be outsiders so they are.
If the person saving that daughter from the fire was named "Awesomo Lad" and dressed in bright neon blue fatigues with a cape and smile and dapper attitude and has been appearing on the news fighting Doombots next to Mr. Fantastic, you better
bet that the average customer isn't going to ask too many questions.
But then take that exact same person -- everything I just described about him -- and add the fact that he's openly associated with the growing number of a genetic master race who has been
confirmed as terrorists, and even the most open-minded individual is going to have some mistrust issues.
Beyond that, it's just what Corp said about preexisting attitudes that may not make sense. Of course a homophobe wouldn't let a lesbian babysit his children, even if she has the same creds as a straight nanny. Of course an anti-semitic wouldn't hire a Jewish employee. Even if they have the exact same credentials and the exact same capabilities -- here you'll note I'm making a none-too-subtle allusion to the X-Men against any other team of heroes -- it makes
no difference at all to the masses because of one single word: mutant.
Case in point: when the original X-Men rebanded as "X-Factor," they disguised themselves as completely human superheroes. The public saw superheroes without the stigma of being mutants and, of course, they met none of the opposition that they would have had they been an openly mutant team.
Sure, it "doesn't make sense" in the way that racism and discrimination most often "doesn't make sense." But I wouldn't call it some illogical comic book thing at
all. We see this kind of "comic book thing"
all the time in the real world; it's so common it's not even startling.
See, even when Civil War happened, the public didn't turn on superheroes because they thought that one day all people wearing tights are just going to band together and overtake the world of non-tights-wearers; they simply thought that they weren't doing their jobs of saving people very well. You're
never going to hear mutants being lambasted for
that; mutants aren't known for saving people in the first place!
Different things, different stigmas. You simply can't group the entirety of mutants together with superheroes on the basis of having dangerous powers. Having dangerous powers is merely a fraction of the issue.
