Edit- y’all are getting salty. Clearly I agree with Lenin that revolutionaries should work in reactionary parliaments. But that is not the same as the DSA who think electoralism is the key to meaningful change, and not a combination of legal and illegal strategies.
But if political specifics from a century ago and a continent away aren't that applicable to the United States in 2021, what are we supposed to do? Seriously engage with modern politics and make a real effort to build a mass socialist movement?
