Well, if human in marvel can get powers Mutant racism can decrease much (in different timelines when most human got superpower they are loved from people and there is low discrimination), if people see mutants as a way to make money, environmentalists and other benefits such as ice manipulators go to the Antarctic to decrease the melting of ice, if magnetic manipulators use their powers to find iron, move meteorites and put space stations in the space, use mental manipulators as psychologists, collect the DNA of people with regeneration and make sure that the entire population can live longer by studying the principle etc... you can not only remove the problem of mutants but also make them the race main, mutants are also perfect for war and space colonization because the X gene allows them to adapt to any extreme environment once activated
read: the (questionable) burdens of leadership of a troll emperor from noodlehammer starting at chap 26 if you want to get to the point. you'd first have to go through all that before even touching on mutant equality. so unless the plan is exodus to another planet, in another solar system, it is just not gonna happen
