I guess similarly, how do you actually deal with the "Individual people are not actually naturally equal in their capacities", problem?
Are these even questions that people who are Anarchists care about, or what?
I'm genuinely not trying to start a "thing" here, these are just questions that I feel like I've honestly just never got substantive answers on regarding Left-Anarchist political philosophy.
Marxists recognize that the prevalence and dominance of ideologies is heavily influenced by material conditions.
The anarchist contribution to this is suggesting that reactionary ideologies are not very stable, take a lot of resources and logistics to uphold, and could be disrupted more easily.
Expropriated capitalists are not much of a threat; you can't raise an army without capital. I will concede that foreign powers are still a threat that anarchists have not come up with as solid of an answer to.
