There might be things you don't like about the DSA, that's fine and valid. But if the left is going to win, we need to fucking cooperate. The DSA isn't perfect, but there's no such thing as a perfect org.
Ask the Floridians and Mainers who's wage got raised if the DSA is too lib.
Ask people from Boulder, CO who are now protected by No Eviction Without Representation if the DSA is too lib.
Ask the Oregonians who now get universal Pre-K paid for by the rich if the DSA is too lib.
All 3 of these were campaigns DSA put in serious work on.
But most importantly, ask the rich how they feel about the DSA. There's no active American org out there (with the possible exceptions of some of the larger unions, who the DSA supports) that has separated more bourgeois from their money.
