It's racist to dislike Canadians just because they're Canadians. Makes no difference if they're white, it's a prejudice against a people because of an ethnicity, a look, the place they came from; it's all racism.

When I was living in the UK a guy nearly got fired because I had an argument with him and he told me to fuck off back to Australia. If he'd have just called me a cunt and been done with it it wouldn't have got any further, but because he told me to "go back where I came from" he was dragged in front of HR and was put on a disciplinary programme etc.

Made no difference we were both white.
