The Panthers did free before school breakfast and after school babysitting and all sorts of actual community building like that. The PSL does protests and craft events and that's it. I guess providing consistent services is an order of magnitude more difficult than organizing marches but it just doesn't seem like the marches are getting us anywhere.
Everything is spectacle. Those are the conditions. Leftism is a fandom. Things will have to significantly change for a lot of people for anything to happen.
