By trying to equate actual free-speech issues with a noted white supremacist and hate speech, maybe?

Hate speech is free speech. I think you're the confused one.

In the US, according to the constitution. But it is mostly not free speech in Germany, for example: https://en.wikipedia.org/wiki/Volksverhetzung

No it isn't. Hate speech proposes reducing freedoms for other people on the basis of their essential characteristics rather than their opinions.
