How much has the X-Men as a reflection of real life minorities changed overtime?

The thing is, most mutants don't have dangerous powers. The vast majority are actually people like Beak. Of course these are superhero comics so the narratives focus on those with skills that are interesting in fighting.

The problem remains that ANY person who's X-gene manifest or is born with them, could have these dangerous powers.
And then it only takes one to abuse said powers or be unable to controll them, that the fear of mutants gains an uncomfortable understandable point.

There is no freak accident involving cosmic radiation or lab experiments gone wrong, no super soldier treatments, no magic/dangerous knowledge obtained, no alien power transfer, no demon/angel ancestors hundreds of years ago, no terrigan mist that needs to be inhaled first. Not even a certain uniformity in powers like most alien or magic species in the marvel universe have. Elements that could explain how and when someone gains power or what powers they gained.
Instead it's just a random chance that any moment any human could gain powers that endanger themself and/or everyone around them.

If a normal human would meet Leech, who could be said to be the least dangerous mutant to them imaginable, how are they supposed to know that it's just a sweet kid who looks mutated and not someone who makes you explode by sneezing or manipulates your mind into walking against a wall for 20 hours?
And that's a situation where a person can actualy see they are meeting a mutant

It's the randomized nature of these powers and the danger related to them, that makes X-gene mutants something quite different than minorities in real life. Because the fear of mutants can be said to have a certain point. Which is why the X-men franchise need to be seen as fiction first and not fully applicable to something in real life.

Of course that doesn't mean that the mutant metaphor for various groups of minorities isn't applicable. Just like the various alien or fantasy races in other works of fiction, it's an easy basis to relate to real life events or situations.
But it doesn't work flawlessly to that end, because there is an element of logic to the fear.
Which indeed can be attributed to the super hero nature, which demands that heros and villains need to have impressive or terrifying powers for big splash page fight scenes. Likewise that the door needs to be open for writers to insert any power they desire on a new characters. From atomic sneezing to turning water into lemon juice.

If being a mutant in the marvel universe would only involve looking unusual or animalistic and would only come with a fixed set of easily recognizable powers. The hysteria about mutants would have less basis.

However one metaphor that could be applied even with fear of mutant having an understandable factor, is of a society in a situation of fast change and how people manage to adept to it or try to enforce a status quo that can't or shouldn't be achieved.
A metaphor that can fit to both normal human and mutant characters alike in the marvel universe.
