The problem the Universities have tried to address under the rubric of "hate speech" isn't really about speech, at all.  It is about power.
.
Democracy functions when people of goodwill are free to engage as adults in civil discussion of alternatives in the marketplace of ideas, so that the public in a democracy can make choices based on reason.
.
But, as George Kennan noted so insightfully in his lectures in 1951, the marketplace of ideas does not function well when we stoke polarisation and tribalism instead of goodwill.  Deliberate polarisation banishes civility, goodwill, adult behaviour, and reason.
.
For example, when people march at night with torches shouting white supremacist slogans, or harass women at abortion clinics, it isn't about freedom of speech.  It isn't about goodwill.  It isn't about reason prevailing in the marketplace of ideas.
.
It is about intimidation.
It is about power.

The universities need to think more carefully about what they are trying to protect.
