I answered you in two replies already, but you will have to define "polite conversation" for this one to make sense. Anyone on the left who calls for or hints at purges in the same way that white nationalists do doesn't even make it onto the national stage. If you define "cancelled" as "losing their job and getting persecuted" then how about Colin Kapernick, for protesting police brutality by kneeling, and the worker who was (most likely illegally) fire by Amazon for pushing for unionisation amidst COVID19?
And being up Bernie Sanders name in "polite" democratic circles, let's see how supportive they are.
Reality is, the far left doesn't get cancelled as much because their popular ideas generally involve democratic control over the means of production and treating everyone like a human being, not revolution, while the far rights "popular" ideas are racism, sexism and the disenfranchisement of the "proles". One of these inherently requires authoritarianism, the other doesn't.
