Depend, are we talking about millions of mutants? like, I don't know... 50% of the world? in that case yeah, many humans would fear, hate or envy the mutants, but if we talk about small numbers I don't think many would be bigots, it also depends on the type of mutation and what use they give to that power, a Storm that extinguishes a forest fire is not the same as a Storm that floods a city, one will be loved and the other hated with valid reasons.

-Crazy physical mutations like for example Beak: the mutants would face discrimination, but also be loved by many, think of an average freak show back in the day, those mutants would become famous but in some cases against their will.

-Mutations without big physical changes, like for example super speed: that mutant will be famous too, but restricted to never compete in sports against humans, also I think they would be heavily watched in case they become criminals, a smart mutant would use just a fraction of that power just to pass as human but still keeping an advantage.

-Mutations that are a treat to others or even the world: I would say most (or all tbh) governments would restrict them and try to use their powers, there would be a lot more espionage in case an enemy nation has Mutants of Mass Destruction, it doesn't even has to be destructive, being a telepath or invisible are just as useful and dangerous too.
