Where most people who say they support free speech are, is this statement: "support free speech without reprisals, excluding directed harrassment, with some level of acceptable reprisals in employment and socially, depending on the context, but at a much lower level than is currently the case, with less arbitrary application of mob justice and employer discrimination"
It's not catchy but nor is it inherently contradictory. It's what I imagine JK Rowling, Chomsky et al would say if you spoke to them about their letter.
I really think it would be useful if the anti-free-speech side of the debate stopped with this semantics and straw men about freedom from reprisals, monarchies, directed racism. I think that a person should be free to discuss eg. spaces for trans vs non-trans women and where to draw the line on sports etc, to what level the BLM is a useful movement, the relative weight of cultural vs economic vs discrimination in explaining different outcomes across ethicities and genders, positive discrimination, without being fired, cancelled or becoming unemployable. That's what most free speech people think, and all these semantic points, false definitions and straw men are kind of a waste of time
