Peace, Love and Equality are Liberal values from the 60s. Before the fall of the USSR, Communism was not even officially about any of that. Equity is their fav word, and equality is marketing. To build itself up again in the post Soviet world, it was forced to use the popular language and call themselves Socialists instead, promising people that they aren't interested in going the extra step to a dictatorship. Also why they often put "Democratic" in their name. New branding
The only difference between Democrats and the DSA is strategic. Dems don't like that Mamdani's approach is too impatient. They don't think the time is right for that.
Kinda like my old reason for choosing Trotskyism instead of other parties 27 years ago. The implementation is a delicate procedure and one way of doing it can "ruin everything" How Communist parties end up hating each other
