Holocaust, Trail of tears, Atlantic Slave trade, Apartheid, The Crusades... KKK, Nazis,.... Jeffrey Dahmer, Charles Manson, A bunch of mass shooters.. I am doing it right? I understand you're not okaying it but in trying to justify the logic those people in a way you are okaying it. It is never right to generalize and in real life despite the things I have point out people are not treating with white people like monsters. Most of society isn't running away from white males because they might be a mass shooter or serial killer. Humans are capable of separating the individual from the masses. Mutants aren't Vampire or Zombies who all have the base trait in world where they are giving out information on mutants,the people aka society on whole should logically do what happens in real life which is a larger group of people be rational about the issue or indifferent not caring and smaller group be irrational aholes.
It is fine that Marvel has different logic from the real world, If Marvel was trying to closer ressemble the real world mutants and superhumans would be treated significant differently. DC does a better job in reflecting the real world than Marvel. Of course this mainly happens because all superpower humans even magic are under one grouping.
