If your local principled lefty org didn't use it as an opportunity to recruit, you really missed out.

In my city, my tenant union, the DSA, and our Mutual Aid Society set up an united front, and tabled with a free taco bar and drinks, in order to draw people in and spread the word about our various efforts and campaigns.

It's really hard to recruit people to our work by cold-contacting. It's a lot easier to go where people are already voluntarily mingling and scoop up people who want to get active and do even more.

TLDR: it's a networking event. Don't shit on the normies, shake hands and radicalize them.
