Free speech can be ‘lost’ by speaking lies and half truths; particularly of the generalizing hostile/critical kind, that can be so common in ‘anti-‘ rhetorics.
That creates opposing factions that instead of trying to understand and be understood try to convince and to reduce each other’s freedom to speak, among other things.
And that can later on be reflected on governments as well, unless that’s where that process starts from in the first place.
Like ‘nature’ the government isn’t any particular entity(s). It is a vague, mysterious authority that is said to control all those things we refuse to control ourselves.
