That protest worked because it was aligned with the right wing.

That protest didn't work, though. Vaccine mandates were on their way out already, lockdown restrictions had been over for a while, and Trudeau only resigned in 2025 because he was taking a beating in the polls. That protest could have never happened and events would have otherwise still unfolded as they did, except downtown Ottawa would have been quieter.

When was the last protest for climate change that committed acts of violence and terrorism against anyone?

Violence? Far as I know, never. Terrorism? I'd argue the 2020 rail blockade qualifies. Which goes directly to my point - did those protestors have their accounts frozen? No. Because Trudeau agreed with them. Put Harper in charge instead and that goes differently.
