The “privatising public spaces” issue isn’t just limited to the internet. To understand the point better the above poster is making you might be interested in reading about how private malls became our de facto “public” spaces.

Legalese and dodgy analogies aside the above poster is focussing on the practical effects of these sites being so big and ‘default’.

On the other hand posting a dodgy opinion on facebook et al largely removes you from the social and physical consequences of saying things that are way outside of societal norms. When you're able to hide behind a screen the range of things you're willing to say increases as does your potential reach. I would argue it completely changes the context to which the ideas of free speech have been classically prescribed. Its worthy of discussion to question do the underlying ideals of free speech apply in this brave new world, or do we need to look at tweaking our ideals to fit the contexts in which we live. I don't have answers, nor would I ever suggest restricting free speech more, I'm just questioning does it make sense to apply it in this domain.

I get what you're saying here, but the sheer number of idiots "fired for saying X on facebook" makes me think it's not true. It lowers the barrier for saying something and increases your audience reach... but also lowers the mental barrier for saying the wrong thing or someone hypersensitive hearing it.

Have you ever investigated how speech is regulated in other countries? I'm Australian and we have a number of restrictions that make speech 'unfree' in the American sense. But I think they're appropriate and on the whole balanced well.

I think you'll find I never advocated for anything, but I am interested in discussing the topic in good faith and finding the real limits and practical implementations - not some fantasy absolutist purism. There doesn't need to be a conclusion from that conversation like you think there does.
