Border communities with Canada

[Bernie Derangement Syndrome Haver]

Being American - and the American political culture and education system - is what I think does it to these people. If the line was a bit further south and they were in Canada, there wouldn't be a discernible difference in voting patterns between these towns and the towns just north of them.

Being American immediately makes the average person dumber and more conservative compared to Canadians, as years of nationalistic, jingoistic American propaganda are drilled into their heads from a young age. This superiority complex also makes them less likely to care about human rights abroad, or even within their own country. And besides, despite all of Canada's systemic inequities, they are far worse in the United States.

Canadians are taught to be civil, caring, introspective, and overall just good people. Americans are taught that they can do no wrong. The education system in America is so poor that evolution is still a controversial subject to teach in public schools. And it's a more religious country, which also makes matters worse. The country is just extremely backwards, its citizens are on average extremely dumb, and they are the furthest thing from the beacon of Western civilization all the white supremacists there like to think they are.

Being American, therefore, automatically makes you a worse person, which is why it's in general a more conservative country than Canada.

Btw, my comment was obviously very tongue in cheek and sarcastic, but I do think just the plain fact that those towns are American and America is a more conservative country is a big explainer of it.
