I define people who are basically on my team politically like this. We agree on a basic humanist, consequentialist worldview of wanting to produce the greatest good for the greatest number of people. And we agree that the basic plan for how to accomplish that is to organize politically, take control of the state, and use state power to transform society in a positive way. We agree that what that basically looks like is increasing the size of the welfare state and democratizing decision making in both the public and private sectors.
And that’s it! We might disagree on the details, but if the above describes you then you are my ally in that project. If it doesn’t then we can still totally be in coalitions together, but eventually there’s something serious that we’re going to have to fight about.
