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.
