Yeah the problem with living in capitalist hellworld at the heart of the empire is that you have two separated insular communities of leftists that are knife fighting rings. One in meetings and one on message boards, and they frequently know nothing about each other.
While the meetings communists sometimes eke out wins like Kshama Sawant, they often struggle to connect to the message board communists who really should be their base. Meanwhile both struggle to connect to society at large.
What's really funny is that most meetings communists I know locally essentially think of him in essentially the same way message board communists think of AOC. Most meetings communists cannot stand his level of yadda yadda when pressed on any specifics he often just goes more general and says things like 'I just want everyone to have healthcare bro'.
Replace Jakarta Method with If We Burn by the same author, it's much more relevant to political organizing at the level the left is at in the West and less of a "sins of the empire" thing.
