On the other hand, how many human characters in non-mutant books are anti-mutant?. I am not speaking just about non-mutant heroes, but also everybody around them isn't racist (even Gyrich is anti-hero rather than anti-mutant).
It is weird. It's as if the X-Men lived in a different world than the rest of the MU. In non-mutant titles, most humans are tolerant, decent people. In mutant titles, all humans are racist.
