I would add that there are some on the left that strongly oppose masks - leftlockdownsceptics.com (which appears to be run by some rather hard-leftists) is running a series of articles at the moment on the subject. They do acknowledge that they are currently very much in the minority though.

Just as the contemporary ‘Left’ has been smitten with lockdown, the curtailment of civil liberties, the expansion of state authoritarianism, and state and Big Tech censorship, it comes as no surprise that the Left is deeply in love with the mask. Every left-organised protest rally, against anything other than lockdown (which fully meets their support), now features masked (and dutifully socially-distanced) protestors. When the Left obsequiously wears the state-sanctioned mask at its public protests, this signals that the Left is fully compliant with official Covid propaganda and the hare-brained and damaging policy response that flows from it. These leftist rebels are missing the huge, elephant-sized, cause in the room – Covid hysteria and disastrous policy overreaction.
