Basically, "Fascism is not a combination of "communism, socialism, conservatism and liberalism". What the hell does that even mean? It's ultra-nationalism, extreme militarism, anti-individualism, anti-liberalism, viewing the State as an organic outgrowth of the Nation (which is usually defined in racial/ethnic terms) and totalitarianism."
It often has mythical aspects to it, as well as religious devotion/fanaticism to the concept of the Nation. Popular religions are often subordinated to the use of the State and to promote its mythos. Or new cults are promoted that suit the interests of the State, often at the same time the predominate religions are hijacked.
Socialism may also be misused and redefined in the interests of the State. If they refer to themselves as "socialist", they usually mean something like "whatever is in the interests of the State and Nation as a collective" and not "worker/publicly owned means of production". Fascism doesn't really have a problem with capitalism and private property.
It's also hyper-reactionary and extremely misogynistic. "Traditional" values are extolled.
I used to be a neo-Fascist/neo-Nazi, by the way. So I think I kind of know what it is and isn't. Lol.
