Now, I want to make this perfectly clear: pro-mutant humans exist within Earth-616. That is fact. Even counting Moira being mutant all along, they have been a thing since the Claremont days:
And to also be clear, they are still around even now: Bendis's run on Uncanny and Grace's run on Iceman both had mutant pride parades with human allies. Even PoX/HoX have some.
But it seems like no one knows they actually exist. Does there need to be more focus on them, showing them battling the racist humans instead of only showing the racist humans, or showing them as being so small they may as well not exist, or do they need emphasis on existing, even if it's mutants doing all the hard stuff?
