My take;
1/3rd of the US people are allies to Canada. 1/3rd of the US people are neutral or don't care about Canada.
The concern though is 1/3 of the people (MAGA) and the government are hostile enemies of Canada. Because of this, Canada needs to consider all of the US as an enemy country. Or at best a county we can not trust at all.
The US is requiring Canadians allow border guards access to their social media when crossing the border. There are reports of them turning away those who are against Trump. Canada should require the same of Americans.
Trump constantly threatens Canada's well being, safety and sovereignty. He directly desires to hurt us with his illegal trade war. We need to take this seriously.
Canada should screen Americans at the border for which party they support. If they support Trump, they should be banned permanently from entering the country. These are enemies of Canada.
