I've often thought about this. It's a proper tightrope. But I'd still rather live in a country where even the knuckle-draggers have a platform to espouse their nonsense, that in a society where dissenting opinions are banned. If they have the right to say it, we also have the right to contest them, using rational arguments. It's how a civilised society works (in theory!)
I genuinely thought this was going to be something made up by Robert Popper. Not an actual thing. Disappointed.
Has anyone got a shrink ray? I've bought the worlds smallest violin, but it's still not quite small enough.
