Technically speaking, fascism is something that is imposed upon you, not something you willingly go along with. I think that falls under the category of stupidism.
Actually not. Fascism is an economic model involving close cooperation between government and large corporations. It can be voluntary for the government and the crony corporations. It’s not voluntary for the population however. That is the difference. Krupp and IG Farben did just fine under Nazism until they lost.
