If the government had stopped at halting the horns, very few people would object, and even then not seriously. A lack of a horn does not prevent a protest.
But that's not what Canada did, is it? They not just remove the protest they froze bank accounts of supporters. That's not democracy. That's a government very very threatened by the protest.
If Canada does not wipe the slate clean and vote away every single politician who was culpable in this, then Canada is not the place it's been advertised to be.
