then I would say your vision is incoherent since you obviously aren't for small pockets "absolute free speech" but aren't willing to commit yourself to controlling speech ubiquitously which would be necessary to prevent the former.
I would say you're not looking wide enough here. Absolute free speech isn't a problem in isolation by any means; but there are impacts to the ability of that to grow into self-reinforcing belief that doesn't match reality. One appears harmless, like a single alpha particle; but the other is an impact akin to an alpha particle chain reaction, or nuclear explosion. Similar impact on society, I would argue.
Could we conceive of a way not to control speech, but to inform or educate or provide information in context--or do something, anything so that it doesn't have the power to self-reinforce and create psychological weapons of mass destruction? What if it's the design of our current social networks around instant engagement and addictive content that's the root of the problem? Could we change the nature and design of that platform without restricting the speech on it whatsoever?
I have to believe it's possible. I'm under no illusion that I know the answer, or that the answer is even something that we have a name for yet. This is not contradictory or incoherent, it's just yet unknown.
While I disagree with the GP, I think you are drawing a false dichotomy and there are multiple conceptions of free speech besides the negative, non-interferential, liberal one that would permit limits on some speech without "ubiquitous" control.
Take, for instance, limits on total expenditures on political speech over $1,000,000.
