Trudeau's state broadcaster, the CBC, said in an article released on Sunday that "freedom" has become a rallying cry used commonly among far-right groups.
That's the excuse, anyway, used by Barbara Perry, who has an actual job as the director of the Centre on Hate, Bias and Extremism at the Oshawa-based Ontario Tech University.
"It is a term that has resonated…. You can define it and understand it and sort of manipulate it in a way that makes sense to you and is useful to you, depending on your perspective," she told the broadcaster.
