Professor Biggar:

Of course people have a right to express distaste of any views they wish. My own view is that universities ought to be in the business of teaching future citizens to express their passionately held views civilly, rationally and robustly, without abuse. If universities do not train citizens to be civil in that fashion, we can expect violence on the streets way down the line, to be melodramatic. Within the law, it seems to me that universities should impose norms of civility on either side. But it is not just a matter of people expressing their distaste at gender-critical feminists or critics of Black Lives Matter or people who think the British empire was not entirely wicked. It is not just that; it is the use of political means to apply political pressure—not rational but political—and it is the use of aggressive abuse.
