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

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.

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.

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.

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.

Yes it is true that pro-capitalist forces have a lot of power. But so did slave-holding racists. We give ourselves hope when we conceptualize capitalism as a set of practices that can be challenged by fighting the piece of the puzzle we feel most compelled to fight.

Communism then defines a society in which there are communal forms for dealing with resources. Many communal forms exist where there are not communist governments. The Mondragon cooperatives in Spain and the thousands of worker-owned cooperatives in the United States, are viable alternatives to capitalism.
