“There's no way I can stop writing, it's a form of insanity.”

Paris Review Interview (1986)

Alan Moore on Anarchism (2009)
Context: I suppose any form of art can be said to be propaganda for a state of mind. Inevitably, if you are creating a painting, or writing a story, you are making propaganda, in a sense, for the way that you feel, the way that you think, the way that you see the world. You are trying to express your own view of reality and existence, and that is inevitably going to be a political action—especially if your view of existence is too far removed from the mainstream view of existence. Which is how an awful lot of writers have gotten into terrible trouble in the past.

As quoted in Born under Saturn: the character and conduct of artists : a documented history from antiquity to the French Revolution (1963) by Margot Wittkower.
