I am not struggling with anything, you are just not making any sense.
By your arguments Canada should neither put tariffs on the US nor really promote a boycott since in both cases, Canadians lose out. So why did you suggest Canada should respond with a boycott?
The talking points might be, that supremacist US attitude is not. It’s been there for decades.
Its not the Russians or Trump there is big part of the US that is hostile to anybody but their, imagined, version of America and places no real value on others even allies.
