(And btw, I'm unaware of anything that exists that is a 'spectrum' apart from the electromagnetic spectrum. To have the quality of being a spectrum, the subject must continuously span a 1-dimensional space. It's a way overused metaphor, in my opinion, especially for political positions which are anything but 1-dimensional.)
So you correctly identify that modelling it as a one-dimensional spectrum is a gross over-simplification. Then conclude that as it's not a one-dimensonal spectrum, it must be a binary property? Rather than accepting that reality is more complex than is easily captured in common language?
I can see how you made that interpretation but that's not what I was saying. Free Speech is an ideal (not a binary property). I doubt that that you will find any human society with a system of laws that puts absolutely no restrictions on speech. That still doesn't mean that you can talk about Free Speech as a 'spectrum'. It's an ideal that ppl strive for, to varying degrees and across different domains. (Perhaps similarly to how Truth is an ideal that ppl strive for; Truth is not a 'spectrum'.)
It also happens to be an ideal that ppl will vigorously promote in certain domains, while betraying / discarding it in others.
