I’m not sure I would seriously call the secret society that the magical community has going on in HP “being oppressed by Muggles”. If there’s any metphor for oppression being done in that universe, it’s in the way the Wizarding community treats other magical sapients (e.g. centaurs, house elves, giants). Even so, J.K. Rowling is a white cishet woman trying to bring oppression to the forefront in her world by using magical creatures as a metaphor for the disenfranchised. While I know plenty of queer folks and PoC that relate to monsters (case in point, my scalie ass), there’s a bit of a problem when that comparison is made by someone who is part of a system that’s had a hand in dehumanizing and othering us.
Civil War came out when I was in high school, so I don’t actually remember a lot of it, seeing as that happened when I was 16/17 (iirc?) and I’m now in my mid-20s. I wouldn’t call what was going on in that arc oppression either. If we want to go into what Marvel considers an oppression metaphor, we need look no further than the X-Men, which comes with the same set of problems as Mages in the Dragon Age franchise.
In the Marvel universe, you can get super powers via an alien bloodline (Hulkling), being an alien (Thor), exposure to magic (Iron Fist), learning magic (Dr. Strange), exposure to a gene altering substance (Spiderman), or just by manufacturing your own (Ironman). In a world where all these ways to gain super powers exists and almost none of them are actually regulated, there’s no way to control who gets super powers, when they get them, and how.
In a world like this, mutants, people who are born with superpowers of varying magnitudes, are supposed to stand out because they’re occuring regularly and are considered a different species of human. Within the world and out of it, the fact that mutants are hated and feared doesn’t make too much sense. There’s little difference between Dr. Strange and Scarlet Witch, when you get down to their powers (as far as I know). That leads me to believe that the reason mutants are feared in the Marvel universe, a place where the superpower roulettes stops on someone new every week, is purely because that’s how Marvel wants to write their comic, which brings us to the big problem: Mutants make a terrible metaphor for oppressed people’s because, in real life, we don’t have superpowers.
In the Marvel universe, mutants range from Skin, who’s power is having a lot of skin, to Storm, who can control the weather. It makes perfect sense to be afraid of them because they could have te pwer to nuke a city, and the average person has no idea who they are and if they’ll use it responsibly. It’s the same thing with Dragon Age mages.
Latinos real world don’t spit acid, black people can’t control the weather, Jewish people can’t phase through walls, and queer folks cannot wield magicks beyond the comprehension of a mere human. The fear and hate levied at the disenfranchised in our world is entirely baseless and unjustifiable.
Granted, I haven’t read Marvel comics in a long time and maybe some things have changed, but honestly? No, I don’t think that bringing up a group of people who are treated like shit by the systems of society, then going “oh but they have godlike abilities” is ever going to be a story that’s told well. The very basis of that kind of narrative device is flawed.
Edit: sorry for the spelling mistakes. I’m on mobile…
