And when they don't control them, they destroy them by un-mutanting them!! LOL.
Seriously, I think in Kamala case, I agree with the quote. Being a mutant wouldn't be a factor on Kamala impact. Firestar, Namor didn't change their impact by being considered mutants. The case of Namor is special, because his impact never has dependent of being a mutant, that is secondary.
Being inhuman is for Kamala the equivalent of being bitten by a radioactive spider: a trigger, but not more consecuential for the rest of her life Her identity it is not tied to Attilan, that is not the mysterious land of her forefathers, Pakistan it is.
