Of course, the X-Men (individually and together) can represent a lot of things, up to and including a generalised concept of "outsider". But I do tend to read them as "gay" rather than your other examples - largely because of the "they come from among us!" thing. Plus the idea that the mutant gene is something biological that they can't help, that can be a plus or a minus for them personally but can't be changed, only hidden.
Yes, but the "invisible minority among us" thing doesn't; I wasn't meaning to claim that the biological aspect only applied to gay people, only that it did so in addition to the other element, which I personally find more convincing.
