There's a curious phenomenon that when a pride of lions lacks a male lion to, presumably, chuck his weight about, lionesses will grow manes and adapt to the traditional male role. This novel has been described as a 'feminist dystopia' and how right that is, as the all-women society set up is indeed dystopian ... at least it breaks away from the idea that an all-female society would, unless it was really short-lived and possible to leave at any time or to expel unruly members, be perfect. If feminism is the radical notion that women are human, then wouldn't it also include the bad side of human nature? You can't spell 'hierarchy' without 'her' (the remainder, 'iarchy', isn't even a word).
Wouldn't even work in Hebden Bridge (lesbian capital of Britain).
I'm also concerned that somehow only women are negatively affected by the future dystopian world they're breaking away from. Let's hear it for a MGTOW community? (though as a supposed Taoist and believing that both sides are necessary, I don't go along with such things).
Way back in the days before I renounced all connections with Science Fiction fandom I recall a comment that a 'load of blowhard men' (blowhard = someone who is vocal about an opinion you disagree with) were sitting around talking about this novel. Having commiserated that they were talking smack about something they knew nothing about, I was informed that they were in fact well-informed.
In which case, I thought, what is your problem?
In which case, also, there is something rather wrong with Science Fiction fandom.
Depending on what you think constitutes 'it' in this case, Terry Pratchett's "Monstruous Regiment" did it better.
