In the real world i would be BOTH pro registration and Pro mutant rights. Xavier and Trask were both right.
Ah , but it diminishes Jean’s status to become just a “Summers-by-marriage”, for the longest time, from her marriage to Scott in 1994 until her death in 1994 (by who I believe was a gestalt of Magneto unknowingly fused with Xorn, unknowingly possessed by Sublime, but thats a whole other can of Xilo LOL) , Jean adopted a hyphenated name , Jean GREY-SUMMERS
But anyway , my point is , since she was not even a “full” Summers like Scott/Alex/Gabe or a blood-Summers like their children Nathan and Rachel , it is the worst optics for her to be having an extramarital fling with a non-Summers while in the Summers House (NOT the Grey-Summers House, mind you). It’s akin to an artist secretly working on a DC project while they are currently on-contract on-the-clock on-the-floor of the Bullpen in the Marvel Corporate HQ Building.
Nobody says "I'm not in the mood" to someone they haven't married or banged recently. Come on, lol.
While human family members of mutants haven't been given a ton of focus in the books, they definitely are present on Krakoa. In addition to the ones mentioned, its clear that its not just high-profile mutants who get exceptions made to allow human family members on Krakoa - the first Marauders series had that issue showing them rescuing a mutant named Lash who was being coerced into working in a shipyard by threats against her human parents and sister. The Marauders rescued her family as well as her, and then a data page said "Lash and her family join a burgeoning society on Krakoa" - so there's definitely precedent that some mutant refugees who had to be rescued and helped to Krakoa do bring their human family members with them.
Even if they didn't allow humans to emigrate there, there would soon be a human population because the children of mutants are sometimes human. If they didn't allow humans, what happens when all those mutants start making babies and a substantial minority are human?
Most even. Of the original five X-Men, I think Beast was the only one who was a mutant from birth. The rest made it to puberty before sprouting wings or shooting lasers out of their face. Ditto the 'All-New' line up. Only Nightcrawler, IIRC, had a fully-expressed X-gene at birth.
I'd imagine that the vast majority of children born on Krakoa have a decade plus of being human to look forward to, even *if* they become mutants. (And Graydon Creed and possibly the Fisher King are proof that even two mutant parents can occasionally pop out a non-mutant kid.)
I am intrigued by how Krakoa and Arakko respectively treat their non-mutant populations. 'Weaponless' Szen and the Fisher King seem to have done okay for themselves on Arakko, but in a society so ruthlessly centered around what you can do with your mutant power, not who you are as a person, it must be distinctly not-fun to be 'just human.' (Even if the non-mutant children of mutant parents are still valued in the abstract for the mutant gene they carry, however latent it is, since a non-mutant like Lucinda Guthrie can clearly pump out a half-dozen mutant kids!)
No all the original and GS X-men were all mutant at birth, not human. They only appeared human bc their X-gene wasnt expressed. Back then tere was little known about X-genes and DNA so it was simple to assume they were all human. Krakoa and tech is so advance now that all kids can be screened to determine if they are actually mutant so there is no need to wait a decade to get those answers
