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.
I'm fine with one that bans dual carding for any org that acts in a way DSA deems collectively undemocratic or reactionary or demands they vote for measures that are not wholly originated in DSA (this is all kind of loose, but so is the demcent ban as is). Like If PSL sent members to some DSA chapter, and then voted to give that chapters funds to a front group of PSL, that should be banned.
