Instead of it always being the mutants who have the decimation events. Decimation and IvX is just an excuse to make mutants look bad and have them be wiped out over and over again. We never see anything like nuhumans being killed en masse, despite there being more than them than mutants at the moment. It just feels hypocritical to always go after mutants and kill them/de power them, instead of just getting rid of super beings in general. If they want less X-Men, stop destroying random mutants. I know things are good now, but how much longer until the next writer comes along and says "wow, over 500 mutants on Krakoa... that's too many, better have another event where they're down to 50 or less".

The thing is, no one actually cares about nuhumans enough to feel the desire to wipe out a bunch of them. They simply don’t matter.

Plus, maybe at some point some one will want to use them in a storyline. Until then they mostly sit in limbo as a failed experiment.

^ plus it's petty. I couldn't care less what they do to Doucheumans. Give me some good X-Men instead of that. Also, Death of the Inhumans is a thing.
