The terms socialist and communist are mostly about describing the world we want after capitalism, and I think they are both important.

In Marxism there are some very unhelpful ideas about the need to push for a revolution that will overturn all of society. Marx gets that from Hegel, and it leads to some very bad politics, such as the hope that things must get worse because that will then turn into the antithesis and get better from there. A kind of wishful thinking then grows out of not seeing a realistic path forward.

I think there is a legitimate critique of reformism, as a politics that is content with making small changes in society without asking for bigger and deeper changes. And revolutionary reforms, meaning actions that we take in small ways to make the world a better place and disrupt some of the ways that capitalism is reproduced.

There is a cultural norm on the left of being afraid to declare victory, which is related to the binary of reform/revolution. Whereas reformists are winning small gains, revolutionaries don't want people to be satisfied with those small victories because they worry this will lead to acceptance of the bigger picture of capitalism domination, and so they find a way to turn every victory into a defeat. In the book, I call for a culture of declaring victory wherever we can.

You build movements and keep people in a struggle when it feels productive. Anti-capitalists have typically been the people in movements who have declared every gain to be a trick of the capitalist class to buy us off. That line isn't very inspiring, and it shows no sensitivity to how social movements actually succeed.

States can be more or less democratic, and so can socialism. I think any ideal society that exists on a large scale, which is what we most likely have in store for us as a human race, will involve some aspects of socialism.

Anarchism as the name for an ideal total social form is a really complicated question. I have never found satisfying answers from anarchists about the definition of the state they are opposed to. Most are opposed to coercive forms of state power. Questions about large scale systems of organization and how they will be funded - those are questions it's hard to get anarchists to give good answers to.
