Cool. You can directly criticize capitalism. Do your grassroots. Don't hate on Bernie because he is using the most effective tools at his disposal. What he's doing is, probably, better overall for the general state of socialist thought in this country than any alternative at his disposal.

You can take direct labor action without denigrating the man for following his path: trying to move the window from inside the system. If you think you can do better, do it. As it stands, do you think you've done more, to actually shift overall labor sentiment in this country to the left, than he has through his "marginally better" moderate progressivism?
