Being in an ML org can often feel more like a reading group and getting mad about theory. Actual praxis is rare, partly cause people who do stuff get the attention of feds and partly cause (at least from what I've seen) the line membership isn't embedded in the working class - lots of grad students or what is decisively called the PMC vs more blue collar work. Plus, when we did real stuff it was like attending a protest as an outside group to show support, like a job action or a violence against women protest etc. It felt often, to me, like we were engaged in fantasy work instead of actually building the capacity for a revolution.

Being in a DnD group or warhammer group means reading a lot of stuff and then at least doing something with it, which makes it unlike the orgs I've been in lol. The action that is taken isn't revolutionary or trying to change things, cause those groups are about playing dnd/40k and painting minis. But it also never pretended to be anything but that. Also, dnd players are infamously flakey and similarly hard to get organized on a regular schedule.
