I have been to the 3 western provinces Nova Scotia & New Brunswick. You have a beautiful country that I have always loved & respected. I was very surprized to learn that all Canadians didn't feel the same about us. It hurt my feelings actually.
In my opinion, at least, the great vast majority of Canadians have nothing at all against Americans, but a lot of them do exhibit anti-Americanism against the country as a collective entity, if that makes any sense at all. I get the same sort of feeling here quite often.
