Racism … it ain’t just an American problem, as this pissed off white Canadian guy proves with a wildly racist and unhinged rant against a liquor store employee.

As happens these days, it all started because the white guy was asked to wear a face mask while inside the store. That ticked him off, and his racial bias against the clerk — a person of color — came pouring out.

He launched into this tirade, accusing the worker of being stupid and brainwashed, apparently by his religion … in the racist’s eyes. The best part is as he’s screaming racist crap, he says his country of Canada was great before “you people” showed up, and “Canadians are the nicest f**king people in the world!!!”

All evidence to the contrary.

When the racist made a nasty comment about the clerk’s beard, they came face-to-face, and nearly to blows. Luckily, there was no physical violence here … but this guy is no Canadian ambassador.
