You sound exactly like the guy being rightfully made fun of in the OP, and this thread. Hordes of comments by nons making threatening comments against White people is "free speech". But, if a single White person responds in kind, even to the smallest degree, all of a sudden it's bad, it's hate speech, and it must be censored.

Traitors deserve death.

That kind of speech is allowed under the 1st Amendment, and it's repeatedly been defended by the Supreme Court.
