George Ciccariello-Maher interviewed: “What is Antifa? A Scholar of the Movement Explains”

Antifa is not a specific organization. Maybe you could call it a movement, but it’s really more an orientation. And that orientation is of course in the name: it’s against fascism and recognizing the need to confront that fascism directly.  As an orientation antifa plays a specific role. It is against something. Most antifa members identify with anarchism or communism of a certain sort. In other words, the radical overthrow of the existing system.”
