Just off the top of my head she could have called bullshit on his framing and segued into talking about socialism: what it is, what it's goals are, how it is relevant to the vast majority of the American working class, what a socialist methodology in building a new world would imply, etc. But she'd have to have those hidden power levels to begin with, which she doesn't. What you see is very often what you get with these things.

Well obviously giving everyone a history lesson doesn't in and of itself build class consciousness. But running away from your own history while celebrating social democracy (which is crumbling elsewhere by the way) doesn't do it either.
