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.
You mean freepers hurt your feelings? I am sorry, you are obviously one of us politicaly or you wouldn't be here (FR). I think we (Americans) are feeling a little defensive lately.
