Outright incitement to violence against others is easy to recognize as speech not worth tolerating.

But here it gets interesting: hate speech wrapped up as "opinions, ideas, and beliefs". At the risk of downvotes (what ev er), I posit that Fox News engages in high level hate speech (not every minute but enough for it to count).

Case in point: Tucker Carlson's "The Great Replacement" agenda. It's thinly veiled white nationalism -- basically arguing that white people are under attack from non-whites. Yes, it gets discussed by him as "what if" and "how come" but it has an agenda that is prepared to be enforced by violence by those who are spooked by it.

I don't have an answer for how to deal with this, but it is in the end hate speech and is not healthy for society as a whole.
