Also. . . honestly, the idea that mutants being the person next door somehow leading to *more* distrust and hatred? Really kind of stretches plausibility. Traditionally, even people who actively hold prejudiced views tend to moderate them for people they actually know as people. There's a reason "No, he's one of the good ones" is a cliche. Anything less than angry screaming KKK membership bigotry is about fear and distrust of the vague, ill-defined, symbolic "other" more than flesh and blood people right in front of you.
( Which means the main place you'll find people rationalizing why the world totally is justified in fearing and hating mutants, will be that place where the lack of flesh and blood people brings out all the worst tendencies people hide: internet message boards. *zing!* )
Essentially, if mutants actually are common enough that any random person is likely to actually know or meet a mutant? Then I would expect anti-mutant paranoia to be less prominent than, say, distrust of the Avengers, because people are going to be more distrustful of distant powerful people than they are of Joe McElroy from across the street who uses his mutant mind powers to clear his yard of dead leaves every fall.
