Which shows that the initial statement "all the people expelled for hate speech in EU could gain asylum in US" is false: expelling foreigners for breaking hte law is not persecution in itself, and of course pro-ISIS advocates would not be illegible for asylum in the US.
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?
