So there is no such thing as hate speech.
That was made up by the left to shut down opposition and never actually defined. They use it (Like "Rayciss") to shut down opposing voices.
The answer to speech you do not agree with is MORE speech against that position. Do not tell him not to post his bigot bile, prove him wrong and don't let them get away with lying. (Everything the muhjoo shills post is distorted and generally disprovable with a 5 second google search.)
