This is what a protest is. (French here). If protesters go as far, and in Canada it was because you did them dirty, then you must sit at a table and negotiate. You must sit at a table and negotiate with everyone in a country. You cannot do someone dirty then complain that they protest.
It’s effects removing the right to protest, and therefore, removing democracy itself. Go live in Singapore?
They became occupiers when they started living in their trucks. There is no right to occupy in the Canadian Charter of Rights and Freedoms.
If they had slow-rolled their trucks to create traffic jams that is a protest and would have been quite another thing (but also generally illegal, e.g., Ontario Highway Traffic Act §132).
If you don't like what the government is doing elect a new government: that's what elections are for. You don't get to throw a hissy fit and mess up other people's lives and livelihood every time there's a decision you don't like.
Every society is about balancing the rights of the individual and the rights of the collective, and their responsibilities as well. About balancing of different rights when they are in opposition to each other.
If you are expecting protests to force someone's hand, that isn't protest or protected political speech, that's coercion. Some forms of that are legal (e.g., strikes), but there are pretty sharply defined limits.
As a sympathizer to the HK protests, I've heard all these talking points before -- that the protesters are ruining the economy and making things miserable for everyone. Usually the protests can really only get so big when there is a shared grievance that keeps getting ignored by the administration.
In the case of HK, the grievance was the possibility for criminals to be extradited to Chinese mainland.
In the case of convoy protests, the grievance was the vaccine mandate in order to work a trucking job that's mostly solitary with minimal human contact.
Crying because your illegal civil disobedience led to civil reaction by the law is the height of "oh no the leopard ate my face" idiocy.
A particularly odious moral framework, mostly used to justify mass murder.
