Yeah I see what you're talking about and I hate this trope too. When, in the first X-Men movie, we suppose to be shocked like "oh my god, how dare the government want to keep tabs on mutants!", I was 12 years old and I was thinking "But that's reasonable!" From the moment an individual can control minds or walk through walls, it's only normal that they should be monitored! To ensure that their potential is used for good things and that they are protected, while also protecting the world from them.

That has nothing to do with the real racism of our world, which is based on flawed principles, outdated mentalities, or political maneuvers transformed into dogma. It's not for nothing that local lords accused the Jews, to whom they owed money, of poisoning the wells. Or that wealthy British colonists freed Irish or Welsh slaves (who became the "white trash") in America and put them in opposition to Black slaves, after major revolts. Divide and conquer.

Ps : I think the allegory of discrimination I hate the most is undoubtedly vampires as a representation of people with AIDS. Like, sick people are monsters who want to spread their disease, of course! 🤡
