I don't personally know a single American that hates Canada or Mexico. In fact, I would say the opinion of Canada is between neutral and quite positive. They've just about never done anything to wrong us, have been a good border partner, and an amazing trade + energy partner.

I also don't know a single person that hates Silicon Valley. Most Americans, in my opinion, are clueless about Silicon Valley, outside of knowing that there are technology companies there. Why? Because the people / culture and politics of Silicon Valley don't matter to them and their day to day lives.

Edit: Only one downvote? Come on, HN. Impress me.
