A death threat against a whole ethnicity is illegal and in no way considered protected speech

No, in America this is false. A true threat must be a credible, present danger to its target. Saying "all people of race X should be killed" is nothing like that.

same goes for libel and threats to individuals.

No. Libel is not illegal, and is still protected against prior restraint. It's only addressable through civil liability suits.

And this is by design.
