Of course. The usefulness, imo, of anarchist grandmas from ages ago is seeing shared experience and what worked (and didn't) in their conditions. It's a great way to displace theoretical discussions that otherwise lack a scientific (in the social sciences sense) basis with real strategies that butted up against powerful forces and succeeded and failed for very specific reasons that we should be careful to avoid - when applicable. It also gives us shared language and examples to make communication between socialists easier.

But yeah, even though I'd like to say that, say, a la Luxemburg is a good idea, we have to remember that Germany was barely post-feudal at the time and fascism was developing at the same time as monarchs waned and capitalists were finishing their economic coup. Current conditions have similarities and differences that are both important. It's not an instruction manual.

Also Western lib discussion of all of this is so goddamn shallow and focuses on psychologically analyzing leaders and generally ignoring historical, economic, or cultural context outside of basic identity politics. Hell they still try to gloss over colonialism all the damn time. The backdrop to a mid-century American leftist is a euphemism like "Western expansion" without an analysis of how this racist appropriation drove the development of these ideas and movements. It's just there. Cowboys pew pew.
