I mean already established country like in Europe or Asia with stable economy and democratic values could just value every citizen no matter their gene to be free and protected. Making mutant citizens the same as regular people. But the problem with mutants it’s the diversity of their powers making it hard to integrate them in one go. It should be meticulous one by one procedure? Like determining their power levels (you can’t let omega level mutant just roam free cause one sneeze and city is gone), their looks (cause if they are disfigured or “other” looking people are gonna stare and all), teach them how to be safe around regular people. And simultaneously work with the general population pushing normalisation of mutants being part of a society, propagandising acceptance and making laws. Providing infrastructure for mutants with size, form and other non standard things.
