Talk:Separatist feminism
Consider that male-only communities like monasteries have operated continuously for centuries.
Nunneries have operated continuously for centuries too but they did not operate in a purely single-sex environment since they were under the supervision of the church hierarchy which was invariably male.
There are plenty of examples of male-only institutions lasting centuries. Are there any examples of purely female-only institutions that lasted for a comparable length of time? Nunnaries don't count as they were under the tutelage of a male power structure - the church.
The hypothesis that men naturally form hierarchical power structures while women seek to govern by consensus may explain this difference in effective institutions.
