Proto would imply that there’s a direct line between them and fascism but it’s more like a deranged series of foot paths that are just as likely to lead to anarchism. Reminder folks from John Brown to Ho Chi Minh had respect for the revolutionaries even with their own critiques, also as I noted there is a far more direct line from the institutions of feudalism and monarchy to fascism. But political ideology at the time was weird and hard to classify within taxonomy, for example the Utopians who were the proto-socialists explicitly were also pro-slavery because they couldn’t think of other ways for mass manufacturing.
