I will read this although I am in the pro-Plato 'camp'. I find his ideas interesting, such as how the Philosophers trained from a young age, chosen in a meritocratic way, rule the state based on virtue. This type of government may seem authoritarian nowadays, but back then, when Athens had a direct democracy which resulted in demagogues and catastrophic decisions (after the lack of a strong leader like Pericles), it was an alternative which could work better. Demosthenes himself blamed the Athenian system of government for giving the edge to Philip II as there could be no fast decisions or consistent policy. Parliamentary democracy solved this type of problem with a relative strong executive government.
Plato did attempt to put his theory into practice by attempting to train a Syracusian tyrant (leader, not tyrant in the modern sense) into becoming a Philosopher King. He failed but it was mostly the tyrant's (do not remember his name right now) fault, not Plato's. Interestingly enough, Aristotle too preferred a Philosopher King to a democracy and even helped a friend of his (Ermyas I believe?) who was a leader of an area in Minor Asia but who was put to death by the Persians.
Anyway, this seems an interesting idea to write about although I do not believe that Plato could be accused of sexism as the very idea of gender equality back then was totally unknown. It would be like accusing an ancient Chinese for not being a democrat: technically you are right, but they very idea of democracy did not exist back then in China.
