One of my fundamental problems with mutant-verse is that there seems to be so many of them they hardly classify as a minority. Certainly they have little to fear, aggression-wise, from non mutants.
Give me a movie where mutants are rare things, less populous, for example, than the number of Skrulls that fit on a spaceship in Captain Marvel. Give them a reason to feel threatened, a sense of urgency and desperation.
