Never read that article. I’ll give it a study and come back.
However right out of the bat I see “anarchists” being used as a blanket term and mentions such as Bakunin, which makes me feel like although useful, this is not the best answer for the problem I am (or at least trying) to mention. Read My other commentary for more context.
I think this is a good start, but still too little rigid. This definition still requires one to define Systems of Domination or institutions of subordination. The examples are a big help, but it is still unclear what falls under those categories.
Do unions fall under those “institutions of subordination”? As an example of ambiguity under this definition.
