Ironically, fascism seems similar to Bolshevism and other historical revolutionary movements in that it has an intellectual vanguard that buys into the ideology, but it gains critical mass from people who are motivated to support it for other reasons. Maybe fear of the other or fear of losing their economic status. This much we can know from political science. But do you know any fascists personally and their reasons for being one? Personally, I am surrounded by fascists. These people support authoritarianism and the crushing of any form of political activism and extra-judicial detention of any inconvenient groups, which they consider a danger to stability. They are definitely fundamentally motivated by fear, but it doesn't seem to be a strong sense of fear, since none of the threats they perceive actually exist right now. I guess it's perhaps more of a sense of general insecurity - they feel they can lose what they have at the drop of a hat to faceless forces they don't comprehend. Also, there's a strong element of brainwashing, where they buy into fascist ideas because they were taught that those are the correct way of doing things. They don't see themselves as fascists, though, and may not even understand the term. A motivation that I can relate to is something entirely different. Since so many around me support fascism, it makes me slightly regret not joining the authorities so I can put my boot on the faces of some of these people. I think they will like it, since they are believers in it. Why not give people what they want, eh?
