Strawman. You’re implying that OP believes hate speech can’t encroach on the freedom of others. Nothing in their post leads me to believe they think that.

From their post:

If someone wants to say there is a master race … Sure: they’re free to say it.

Tell me where discussions of a master race will lead, if not putting down the lesser races. Tell me how that doesn’t affect their freedom. Tell me how that’s not hate.

Many seem to agree on “Freedom of speech, as long it doesn’t harm others’ freedom,” but too many don’t understand what harm is.
