Although the article you provided uses the DSA and unspecified "unions" as examples, the article does not clarify explicitly whether or not other leftist orgs are masking or not.

I was simply asking a question as I'm not intimately familiar with what these organizations are doing. It's unfortunate to hear from your response that PSL and others aren't doing better, in a time when just wearing a simple cloth mask is literally more than 99% of people around us.

P.S. Honest question, you said in another comment that you were surprised by "negative" responses to the article, but if you're counting my comment above in them, were you expecting people here to be happy about people not masking?!?
