Kant would argue that you universalize all forms of theft by stealing so if we ever see stealing as immoral then it is wrong to do as it fails the metric of the application of the categorical imperative. I mean I don’t buy into Kantian morality but if one did he might make less of a distinction between them.
Blackshirts and Reds by Michael Parenti is one of the best books about fascism.
Georgi Dimitrov is also highly worth reading regarding fascism. The Fascist Offensive and the Unity of the Working Class especially so.
