I believe you mean that separation of hate speech from freedom of speech rights isn't easy.
There's an essay I found pretty unique, "Reflections on Debating The Right" on Current Affairs, explaining why much more public debates would be helpful... of course, that website could well be blocked soon in Australia for their articles on Palestine, given the precedents now set!
People on the right (the proles, not the rich people making money off the whole affair) don’t want to have honest intellectual discourse. They want to ‘own libruls’ and be smug (despite their choices actively hurting their livelihood and their lives leaving little to be smug about).
There’s nothing to debate, they’re just idiots. Easy to fleece idiots considering how easy it is to make money by throwing out a bunch of controversial statements and then retracting when their audience has moved on.
I hope to come back to this debate in a few decades and see that Robinson's pieces on debating the right, along with Mark Fisher's "Exiting the Vampire Castle" and Benjamin Studebaker's "The Left is Not a Church" will be considered important overlooked resources.
