I studied Classics. Athens, the cradle of democracy, was a city where women had no rights and everyone with enough money owned slaves. Young boys were routinely expected to have romantic and often sexual relationships with older boys and men. Ancient Rome was marginally less dreadful for women, IIRC, but still very bad in modern terms (women literally property of the father until married, when they became property of the husband), and also a slave society, and of course they were the supreme colonisers, appropriating other people's cultures left, right and centre as they gradually took over most of the known world. I can only assume my subject is going to be obliterated. Goodbye Homer, Hesiod, Aeschylus, Sophocles, Euripides, Aristophanes, Plato, Aristotle, Thucydides, Herodotus, Pindar, Sappho and many, many others. Valete, Virgil, Catullus, Horace, Ovid, Cicero, Livy, Caesar, Plautus, Terence, Juvenal, Martial, Lucretius, Pliny etc. Goodbye in the process all the underpinnings of Western thought.
Oddly, when I was a student in the early 80s, it was felt possible to inform us about the nature of these societies and let us draw our own conclusions about them. That would probably cause some university administrators these days to have a panic attack.
