The books do not tell us every mutant has the same experience, other than when there were 198 of them rounded up in a camp.
Also, the percentage number of 'humans' who hate and try to wipe out 'mutants' is probably statistically less than the other way around. While I do see examples of poor writing in recent years (and a huge offender on the main book right now) that narrate using that crutch, I think we as readers can do better and take one second to think about what the reality of the every day life is for many people in the MU and not rely on the shock value writing that has become common.
