I suspect the GP had EU far right dudes in mind, but most such 'hate speech' is often basically "slander and/or harassment that happens to be also racist" and typically ends up with a fine: hardly 'persecution'. And even if we go from "all the people" to just "a handful of ideologues": why would the US say no to ISIS but yes to Nazis?
