This is not true though.
Fascism only sounds incoherent if you take it at face value, but it is integral to protecting and preserving the liberal capitalist order during times of crises. Italy and Nazi Germany served the role of crushing left wing and working class movements in post-WWI Europe following the success of the Bolshevik Revolution. Fascism saved “international capital” in Europe from falling into the hands of the “Leninists”, and continued to do so well into the 21st century.
I don’t take fringe ideologies (like national bolshevism, lol) seriously because they fall apart at the slightest scrutiny under materialist thinking, but fascism - fascism is well grounded in reality and should be taken extremely seriously by everyone who considers themselves on the left. There is a reason why fascism as an ideology historically succeeded while many others never even got off the ground.
Clara Mattei’s The Capital Order is essential reading to understanding how liberalism invented fascism to preserve private property ownership and wage relations during the turbulent years following WWI, and provided compelling arguments, using contemporary political and economic records, to show that both liberalism and fascism are two sides of the same coin whose functions synergistically protect the capital order.
