Against fascists it's primarily for self-defense. Of course the organization itself involved in self-defense militia could be used to take political power in a socialist revolution if popular and massive enough, but primarily it's about protecting yourself, your family, your identity group and your class. And I'm not sure moving to Ghana or Costa Rica would do much good against the world-wide reach of the American capitalist empire. Maybe for a while, but anytime a fascist USA wants to attack, they will attack anywhere in the world. That's obviously true of the current bourgeois American empire, so I don't see it being any different in a fascist America. That's why, IMO, it will need to be fought here.
And we ALL have a personal stake against fascism. The Jews were not the first people the Nazis went after when they took power in Germany. They went after the communists, socialists, and trade unionists first in order to secure their power because they knew that an organized and militant working class was the only group with enough societal power to stop them. Of course they used the racism of anti-Semitism to fire up the petit bourgeoisie and dissatisfied elements of the working class and criminal elements or lumpen proletariat, but they didn't go after racial minorities immediately. They had to secure power first.
And I do believe that Ukraine is a model of the societal forces involved in a fascist movement. Just because the outsider group in Ukraine was Russian speaking Slavs rather than black and brown Americans doesn't make it a different pattern. Just like the Jews weren't black or brown, for the most part anyway, in Nazi Germany. Fascism is all about the social forces involved rather than the different identity groups.
