This is a caricature. You've set a mainstream right-wing identity flaw (it's represented in the CPC leadership race) against a crazy fringe who have no representation in the mainstream of "left" politics.
Examples of "Representation in Mainstream of "Left Politics:"
2017 New Years Resolutions for White Guys on MTV
Brock University's "White Privilege" Symposium
Black Lives Matter Toronto to receive "Race Relations Award" for inflaming racial tensions.
Pride Toronto bans Police from Parade
I found this after a cursary, two minute Google search. You obviously have an unusual definition of "no representation in the mainstream of 'left' politics"
A more reasonable duality would be setting a Richard Spencer style ethno-supremacist against its mirror.
Richard Spencer is widely panned as a White Supremacist, and I don't think you'd see a single CPC candidate (besides Leitch, maybe) dumb enough to openly meet with an ethno-supremacist. I can't say the same thing for my own Liberal premier. There is also a tremendous difference between racist ideas being vetted in a leadership race, and the election of said holder of ideas.
And again, you seem to be applying community responsibility
I'm talking about what narratives that we collectively, as Canadians, should be legitimizing by our own institutions. Any attempts to divide or silo us by colour is reprehensible, and shouldn't be parsed.
If you find something that a person says odious, that that person identifies with the left or the right doesn't paint any organization with that same responsibility.
That's a cop-out. If this individual is in a position of representing an organization, there is an implicit acknowledgement of their views. It's why people lose endorsements, jobs or advertisers all the time. It's why The University of Toronto asked its own professor to stop talking when he had an opinion in contravention of theirs.
If you do you are falling in to the same identity politics you claim to despise.
Calling for consistency in discrediting identity politics isn't falling for identity politics.
