In my experience these self-given-labels just express the views of some founding members and are often used to clarify who they do not want (capitalist, misogynist authoritarians) and who is welcome (left leaning people, women, people who know how to treat women, people who can respect flat hierarchies).

I find it a bit edgy to self label an encouraging like that, instead of explaining the meat of it (we are anticapitalist, because..., we are feminist, so women are welcome, we are anarchist, so our organization is structured with a flat hierarchy). Since it is an anarchist space, that is anti-authoritarian you probably won't find much indoctrination.
