> In other words, anarchism presupposes lack of significant prejudice.

That seems to put it in "fun thought experiment" territory.

Or "conditional probability" territory. Of the people who would choose to espouse a philosophy of treating everyone as equal, it is unlikely to find someone significantly prejudiced.

Espousing ideology isn’t the same as believing it or living it. The moment the threat of the state recedes, and sometimes before, anarchist violence turns inwards; race, sex, and gender expression are just as suitable as status markers for anarchists as anyone else.
