What seems to be your issue?
Are you a cop?
Why are you siding with them?
I read it as a misunderstanding. Think canuck thought you meant backfire against the truckers.
OK sorry
from your wording, I thought you meant backfire on the protestors ... if you’re supporting them, I apologize
I think he misunderstood your wording and grammar.
It could go both ways in that context. Hopefully the truckers fail, or hopefully the police fail.
