the left turned on masks when Trump started wearing

They did? I never see a leftist without one unless rioting. The ultimate virtue signal is the mask that "shows you care about your fellow humans". Of course, the hell with YOU; your mask doesn't protect YOU. But who the fuck are YOU? You're nothing.

Your sole value lies in "protecting the collective", and only in the manner prescribed for you from on high. Obey, slave! Or else PAY THE PRICE.

That's the core essence of communism.
