Facepalm

I don’t believe that fascism can be defined as an ideology, because fascists aren’t ideologically coherent.

It very clearly can't be one coherent ideology, just like liberalism isn't, just like communism isn't. I'm definitely not trying to claim even those individual types (e.g. Italian Fascism, Nazism) are consistent, internally logical, or any of that. Rather, there are common themes, ideas and features which group them together and distinguish them from other ideologies. These groups form a model of relationships between values, ideas and behaviors.

The reason I bring historical circumstance into this is because this model acknowledges attributes like militarism and class collaboration as core components of fascism, with the implied question: why did militarism and class collaborationism take hold in some cases (where a fascist regime rose) and not in others (where it fizzles or is defeated)? Historical factors like World War I and the subsequent wave of communist uprisings are related to why fascist ideologies were developed and were supported by many ex-military and bourgeois. And that is why the conservative racist chauvinism in the neoliberal US and Europe is taking remarkably different shapes to the fascist movements of the 1920s, despite those similarities which guide your definition all being present.

An example of this is neo-Nazi movements like Patriot Front and their international equivalents, which do not receive the blessing of the owning class, which are floundering and failing worse than the British Union of Fascists. There are reasons why they can't replicate the same political strategy and tactics as they did before, and some of those reasons are because we now have different environmental factors. They can't recruit defeated ex-servicemen en masse, so they now primarily recruit vulnerable alienated nerdy teen boys. They can't yet (and often don't want to) earn the blessing of the bourgeoisie at scale because the populations have shifted in a more progressive direction. So then we see neo-Nazi 'Siege' tactics emerge, which are inspired by late-1800s Propaganda of the Deed anarchist tactics, and that is not going well for them either.

Then, we have White Nationalist and/or Christian Nationalists as politicians and billionaires. They often don't want militarism or have military values. They probably don't want class collaboration (because they're winning in the class struggle). So like their goals, their tactics and strategies will overall differ to the fascist movements, despite the shared chauvanism.

If you have suggestions on how to adjust or change the definition, it would be helpful.

I worry that it is too broad, discarding what makes fascist movements unique. I believe the part about violence is ultimately redundant, as I assume systematic chauvinism itself makes individual violence and violent repression likely. The definition, in my view, is really just describing a strategy of using chauvinistic hierarchy, and I don't understand why that is special enough to be called 'fascism', if anything that will just trivialize fascist movements and make the word itself banal, since for example xenophobic chauvinism is a strategy used by almost all governments worldwide, and which does lead to domestic violence.
