I suppose it might be technically true if one considers only the number of people "discriminated against" and includes everyone who's politically/socially associated with that group. The number of native Canadians is much smaller than the number of people who feel that anti-COVID measures infringe on their freedom, or at any rate don't want to wear masks, get vaccinated, etc. There are more Trump supporters (who, by implication, are okay with his stance on COVID) than there are members of any non-white ethnic group in the U.S.

If one takes into account the justification of the forms of "discrimination" and their consequences -- and how easy it is for the unvaccinated to become vaccinated -- the assertion is preposterous. Nobody is lynching unvaccinated people or taking them for "rides" out of town on bitterly-cold nights. They're not at elevated risk of police violence merely because they're unvaccinated.
