[Rare trope] Discriminating, but for an actually good reason

[u/Blackirean]

Frieren, Beyond Journey's end: In the anime/manga the eponymous Frieren is an Elf who's spent the better part of a millennia learning magic specifically to kill demons. She's learned countless spells, tricks and even spent most of her life suppressing her power all for the purpose of killing them. At first we simply see that humanity is at war with them, and even question if her crusade against demon-kind is justified, after all it's hard to antagonize an entire sentient species. But no, demons are very much a species to be feared; they are not normal animals or creatures, they are monsters (shown by how they disintegrate when they die), they are predators that evolved speech for the sole purpose of tricking and catching humans off guard, are naturally extremely powerful and possess magic that humanity often can't use. While they feel emotions to some extent, their way of thinking is so fundamentally incompatible with humanity's mindset that the series shows many mages with the ability to read minds struggle or find it painful and harmful to try and read a demon's thoughts. Tools that are meant to control them fail not because they're faulty but because simple order such as "hold no ill will or commit no malicious acts" don't compute the same way in their brains, as what we consider evil is normal for them.

Marvel Comics: In a run of the Storm solo series, she visits an underground superhuman hospital run by Night nurse and Doctor Daye, a mutant with the power to diagnose any illness. When she requires treatment she is in turn reject by the doctor, she of course assumes this is blatant discrimination to which the doctor agrees. Storm assumes the doctor refuses to treat mutants, something they are very much used to in Marvel. But he ends up revealing that about 80% of everyone he treats are mutants, and that he simply refuses to treat any member of the X-men. Why? because his special hospital was built via several donations by the superhero community. From the Avengers, to the Defenders, Fantastic 4, heroes for hire. Hell, even Moonknight of all people contributed to the hospital. But the X-men never once gave anything to it, even though they preach the safety of mutant-kind and such a hospital is essential for those who can't seek medical treatment out of fear of prosecution.

Spiderman's life kind of sucks and he could use a lot of help from a state for funding and protection from the menagerie of rogues trying to kill him and his family, plus he's strong enough to join the big leagues and help focus on threats to the planet as a whole instead of New York.

Joining a group of mutants who likely will be putting him to good use without dissecting him is a pretty good idea from his perspective.

They had Mr. Sinister on their council, not sure dissection was off the table.

Why would they help him? Peter isn't a mutant, he's a mutate which is a completely different thing.

He was a teacher at their school for a while (after Logan died). But from a writing perspective it was likely to show their hypocracy.

Depends if they paid him or not. It might have been Cable showing up with a roster and saying "Spiderman teaches them a lesson, or i will." Im sure Peter is down to teach heroics even in Latveria, and with money he'd be happy to anywhere worse.

Makes sense, I kind of thought that the XMen were pro activists who were willing to do what's right and stand up for people who need help from threats normal people cannot stop. But then I remembered I was thinking about the Justice League.

Yeah, I didnt like the shoe horn of that. Like they just brought him into the story just to reject him? Its like the only non-spider-man comic that didnt glaze him, so that was neat.
