now, that said, free speech is about the limitations of government actions, it doesn't apply to behaviour between private individuals in personal communication, or over any kind of market.
so, when i say that the state has no grounds for interference, that doesn't extend to the behaviour of private individuals, who also maintain freedom of association.
what that means is that if you don't like somebody's facebook posts about the prime minister or "muslims", the proper thing to do is, in fact, fuck off - which could mean deleting them from facebook, not inviting them to parties, generally snubbing them in public, not sending them christmas cards, etc. you don't have an obligation to be nice to them, or associate with them in any way. that's your own right. saying certain things in public over a platform may lead to social consequences, and it's up to the people saying them to weigh that before they do it.
but, it's not the role of government to police speech.
and, that view is at the very crux of our culture and our civilization, and is something worth holding on to and fighting for.
