What’s wrong with the radical critique of the People’s Climate March?

Last Sunday’s march was an important step toward building a popular movement for climate justice, which, in turn, is a necessary condition for more radical actions… Having the most radical-sounding solutions in the world is all for naught if those solutions are only believed by a relatively small number of self-identifying radicals. We have to engage broader social bases by meeting new participants at the on-ramps by which they initially enter into collective action.
