(he also does not agree on hurting humans fascists indiscriminately because not all humans fascists are rabid racists)

This is where your rebuttal faltered. Not everyone out there is a fascist

Magneto wanted to push, hurt, kill everyone regardless of their stance towards mutants

Ironically, thinking everyone “else” deserves punishment is one of the hallmarks of fascists

Hurting humans indiscriminately would translate to hurting white people indiscriminately, not fascists. That’s the flaw in your reasoning.
