Kinda skimmed because that’s a really long essay, but:
Fascism is a far-right, authoritarian, ultranationalist political ideology and movement, characterized by a dictatorial leader, centralized autocracy, militarism, forcible suppression of opposition, belief in a natural social hierarchy, subordination of individual interests for the perceived good of the nation and race, and strong regimentation of society and the economy.
Fascism is a fairly specific thing. It’s not just anything that’s not democracy. Overapplying the term is a tool that allows you to condemn reasonable stances as absolute evil. Note that reasonable, used here, does not mean ideal or without caveats. If you can condemn every stance other than your own as absolute evil, that is radicalization. Radicalization can have its use, but it’s a dangerous thing. It needs to be focused. What is “Punch a Nazi” when capitalists are fascists too?
