Of all the things you could critique DSA on, this is the hill you're going to die on? 
DSA deciding to do a mask mandate at this event is unequivocally good and based. Shut the fuck up, you fucking dipshits.
Imagine being this much of a fucking goddamn crybaby about masking. Eat shit, you ableist fucks.
One of the biggest lessons this pandemic has taught me is the astounding number of people for whom leftism is really just performative, and that when push comes to shove, these people will make the biggest fucking stink about having to do something even mildly inconvenient for even a single fucking event or context and show themselves for who they really are.
Dear leftists that don't want to mask to protect others (including the vulnerable), please post your sad faces on Twitter so I can at least get a little satisfaction from this pandemic and all the suffering I get from your selfishness.
Even in 2020-2021, during the fucking mask mandates, I had to stop doing heaps of shit I enjoy because you dipshits can't follow simple requests to save lives. Go watch a film? Nope. Coffee shops? Gone forever. Gyms? None for me. Mass transit and food shopping? Yes because I have to, but fuck I'm terrified. Work? Sadly yes but you fucking need to put the fear of death in me.
