I think if the story ever presents it as a non government controlled treatment that people could willfully go to, and that was THE ONLY WAY that it was used, there would be no problem.
But it’s not written in the story like that because I guess in story, someone out there with an anti mutant agenda would find a way to weaponize it.
Does that mean no good therapies can exist in real life without it being weaponized? I don’t know the answer to that but the comics say no it’s not possible (since every time it’s brought up, someone tries to weaponize) so I just go with it *shrug* .
I guess what I’m saying is I don’t need the parallels to be exact for me to still appreciate what they are trying to say. Once we acknowledge that the people in 616 act in ways that differ sometimes from our world, it’s an easier pill to swallow. As long as there is enough consistency elsewhere.
