There are always slogans like: "property is theft", "no gods, no masters" and "from each according to their ability, to each according to their need". I like to mention: "if you don't work, you don't eat" and apply it to the capitalist class.

Once the dialog gets to labels, I am direct with everyone but police.

I am an anarchist. I want to eliminate the state's monopoly on violence and the heirarchy thereby imposed by said state. Humans are naturally social and collaborative.

I am a communist. Workers own their labor and the means of production.

Definitions solidify from there if the person cares to have a dialog on politcs and philosophy.
