anti capitalist fascism exists

inevitably, all political projects in this mode of production will tend toward neoliberalism in practice, unless it has idealist anti-politics ancillary to it, or something destabilizes the entire framework.

In fact, fascism is driven historically by the channeling of alienation, which of course will have anti-capitalist tinges from time to time. But this is just spectacle until it starts to drive anti-politics to the fore of the alienated's minds. This doesn't usually happen when they are winning politically, although it can certainly confuse things and play to their advantage by eroding other's understanding of what fascism is (a political project of manipulating alienated downwardly mobile people back into hegemony, even if it is a chaotic hegemony)
