The 'Them' that you're talking about are not Left at all. If the very first premise of this interview was that the Left are not about ideas, then you need to have ideas because otherwise these conversations struggle to be more than finger pointing at the very same mouse wheel of privileged people. The intellectual Left are hobbled by their deep catchphrases and constant critiques of other Leftists, in fact they themselves lack ideas. Communicating ideas is a much tougher job and it's painful to hear these conversations.
