And this is the stuff that needs challenge. Specifically then, when has the state tried to silence Robinson, other than when he's actually broken the law? Links please, or you're making it up...
He's not a heroic rebel, a little man standing against oppressive authority, he's a criminal thug who tries to intimidate anyone who dares to challenge his beliefs. He's shut down because free speech isn't free when it encourages hatred and violence, it has an actual human cost.
If you think you've got an authoritian state now then imagine what you'd get under the likes of Robinson; look again at the Hope not Hate article above, and look at what he actually says and does.
Then tell us what part of it is wrong; it's a chance to prove your and his superior intelligence so please don't keep us waiting...
