A certain sect of the Purifiers hated super powered beings too.

The Inhumans should have been hated more. Keep in mind that most superheroes or at least legacy superheroes got their powers by luck for pure accident or just something not achieved by the an ordinary person.

Being a mutant or having a neighbour thats one is a higher probability. They're not a goverment weapon like Steve Rogers or in some cases worshipped because they're a God like Thor. They're the student in your class that can cheat on tests, or has an unfair advantage. And its evolutionary while you're an ordinary Joe soap are left behind.

You feel you're obsolete that you're being replaced and an evolutionary outdated amoeba.
