Its more then identitarian, it's about breaking distinctions between the moral and the executive, the corporate and the republic, binding people together by using various bureaucratic institutions to govern every aspect of people's lives, towards a singular (nebulous) goal, the way cells in your body work together towards singular goals governed by your attention.

If it's hard to define fascism it's only because our modern western sensibilities don't want to confront just how fascist we are, or in fact wish to be. We want to be part of a whole, to consider the state as parent, to be absolved of the responsibility of sovereignty and liberty. We want to be told what to do, what to eat, how to shit, who we're allowed to be friends with or consort with. We want to be absorbed into the machine.

Fascism is part of human nature. To be fascist is to be "saved", but not in a Christian sense. Its to be freed from identity, to have status without any personal responsibility at all for the moral integrity of society.

In that context fascist societies are dangerous, because people can do terrible things when they feel that they are merely tools of the state and not personally responsible for anything they do.
