Why Are The X-Men Outcasts?

Every super hero with a super ability is welcomed into society. Mankind sees Superman’s abilities as a force for good in the world. Batman was a little scary before the people of Gotham understood him, but he is the protector of the city.

But, in the X-Men world, mutants are treated as second-class citizens, despite their super abilities.

Why?

Is it because X-Men have free will? Superman often saves Metropolis because it’s his duty. Batman protects Gotham because he wants to save it from the kinds of criminals that murdered his parents.

Do X-Men have any duty?

X-Men are often compared to minority groups as though X-Men are outcast because they’re minorities. The bigotry held against them is what unites them. But X-Men have clearly superior abilities compared to normal humans – abilities that could be used for good.

The conflict between mutants and normal humans is often compared to real-world conflicts experienced by minority groups in America such as African Americans, Jews, atheists, Communists, the LGBT community, etc. It has been remarked that attitudes towards mutants do not make sense in the context of the Marvel Universe, since non-mutants with similar powers are rarely regarded with fear.1

Are we really to believe that X-Men are not accepted by humanity simply because they’re mutants? Humanity wouldn’t put aside any bigotry once it saw the benefit of mutant powers, similar to the way they highly regard Superman and Batman’s powers?

Which world is more realistic, the world of Batman and Superman, or the world of X-Men?
