In the case of Wexit, Tamara Lich was a founder, and she buddied up with Pat King for the fundraiser, who is a self avowed white supremacist, like he's literally on twitter saying white people have the "strongest" bloodline.
If someone who is involved with multiple "Canada for Canadians" movements joins forces with a known racist, I would take the odds and bet good money that person is a racist.
Sure Wexit is a separatist group but I fail to see where you are getting racist from.
