Looks like Socialist Alternative is going to try to make DSA form a workers party by having some of it's members join DSA.
Current DSA by-laws allow for chapters to expel members for being in Democratic Centralist organizations but its not automatic. It also seems like SAlt isn't telling their members to join en-masse, just a few to push for a new workers party at meetings.
My DSA chapter isn't happy about this but it seems like most apprehension seems to be from their experience with individual SAlt members, first and the rudeness of the tactic, second. But there seems to be little consideration of their goals.
That's the dream all the Trot microsects have. Except what happens when they do entryism into left groups is they engage in tiresome bullshit and fights for leadership. If they're successful, a lot of the group that they entered leaves, because now their group is Trot and the members didn't enjoy all the bullshit, leaving the Trots in control of the name of an empty group.
