Perhaps recognizing that the accusation of extremism won’t stick, some critics have grasped for an old chestnut, which is to point out that Poilievre’s rallies largely draw white folk and not so many people of colour. 

“The implied guilt-by-association is a classic tactic of the left. The objective is clearly to imply, if not state explicitly, that a gathering of mostly white folks is somehow racist or even white supremacist.

This line of argumentation is both pernicious and insidious. It assumes that unless there’s a statistically representative sample of the entire Canadian population — or, better yet, an over-representation of minorities — an event or a cause only represents the interests of white Canadians and therefore somehow should be discredited.”
