Tell that to the eunuchs. Castoriums were still running in Morocco in the 60s.
True; from my understanding, tho...most of those Moroccan eunuchs we know about were 16th century onward...
And then among those eunuchs in the Ottoman empire, the 19th century onward...
Arab-based Muslim slavery of Africans goes back to the 7th century...so that's 8+ full centuries of killing off newborn males.
My mother used to give me Castoriums in the ‘50’s. I think it was to make me shiite.
