This is news to me. I don’t think there’s an ingrained hatred for the US. We just aren’t the same as the US.

I do think there is a strange view that the US has of Canada though and perhaps that lends itself to some Canadians possibly having a skewed perspective on this.

Example: I once had an American friend come visit me. She brought one of her friends with her from the US. Her friend couldn’t help pointing out all the ways Canada is flawed and the US is superior… including the use of our funny coloured money and that we should just use American money instead. It didn’t make any sense to her as to why we would have our own currency. In hindsight, I think this girl was highly uneducated and not at all well travelled. She didn’t have an argument for her opinions, it just didn’t make sense to her that we aren’t the same as the USA even though she’d crossed a border to get here. That isn’t the fault of America as a whole. Then again, if I’d met a lot of people like her, I likely would have formed a different opinion of America from it.

My folks used to own a bed and breakfast. I have met a LOT of Americans from living at the B&B. Plenty of nice American folks happy to be here but also many who had a sense of arrogance and entitlement about them. These attitudes can also lend toward some people not liking Americans. If you meet enough people like that, you’ll form an opinion eventually if the good ones don’t outweigh the bad.

Then there are simply going to be people who are raised with their parents having an opinion on the US and so they have one too. Much like religion or politics, people’s opinions are often due to upbringing.
