IMO it depends very much on how those positions are being forced on those attending. Since this is about permacomputing I suspect not all that much.

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.

This is where I think the problem is.

Once you start appending political identifiers then the purpose of an organization becomes more than just about X, but X according to certain values to the exclusion of others. There's nothing wrong with that but I could see how it can be viewed as disingenuous when it's insinuated that the organization is more open/general than it is apparent.
