That kind of thing does kinda raise the question about quality of life for a human living on Krakoa especially right now. Currently, we have a confirmed number of 2 humans, Shogo and Kyle, living on the island. What must that be like especially with there definitely being mutants living there who at best look down on humans and at worst despise them?
Can you really say that they wouldn’t be? Sure the X-Men wouldn’t but there are no doubt people on the island who do discriminate against humans. Hell, we’ve seen the likes of Esme referring to humans as monkeys and even children throwing around terms like “flatscan”. There is no doubt in my mind that there is some degree of discrimination against the humans living on Krakoa especially when mutantkind finds that to be their own private piece of the world away from humans.
Prior to the Crucible, there was also Melody. You are right in that 2 are confirmed but I think that issue set up that there are at least depowered former mutants on the island waiting for their chance at the Crucible to be reborn
There are mutants on there that we know for a fact hate humans and see them as lesser than. I dont think its a leap to assume that they'd view humans on Krakoa with the same negative lens that they had before the nation existed
There are also mutants who would be protective over them as well given their position on the island. Those mutants’ disdain for humanity didn’t come out of nowhere and it isn’t simply because theyre seen as “lesser than” but because of their entire lives experience before Krakoa existed.
So if it’s nebulous, why assume the worse to fit your mold of Krakoa?
