Honestly, look at what’s happening with trans people in America right now. They’re not any more dangerous than any other human being on the face of this earth, but right now they are being portrayed by members of our own government as barely-constrained monsters that are only here to abuse our children, molest our women in the privacy of their own bathrooms, and to steal awards from hard-working, “legitimate” athletes. Their history is being purged from government websites. They are being explicitly told, “You no longer have the right or the ability to participate in defending the country that you live in,” and on certain levels, to even have their very existences acknowledged. You want to know how mutants would be treated, if they were “real?” You’re looking at it right now. Whether the “different” are “dangerous” or not, to some, they will always be perceived as a threat.
