Most Slaves Have Always Been Female

There's nothing new about women being integrated into the workforce. Slavery, with the exception of the plantation economies in the Americas, has always been largely female.
Ever since woman first said, 'I could do with some help with the housework' and man rushed to the neighbouring tribe to kidnap some girls and kill the men, slavery has been largely female.
Indeed, work - life itself - has been largely female.
It is only in the last couple of hundred years - since the ultra patriarchal French Revolution - that the absurd notion has arisen that what the boys do is what is important, and that women exist to serve them.
In ancient times the Greeks, just like the barbarians that they despised, would enslave conquered people. When they destroyed Troy they killed the men and enslaved the women and children. The men weren't really necessary or useful - the women were.
The Arabs, the Turks and other Muslims such as the Tartars were big on slavery too. Nowadays it is fashionable to talk about the centuries of Islamic domination in Spain as some kind of golden age, but the Christians were very careful to keep an unpopulated military zone between them and the Muslims, who liked nothing better than raiding for slaves.
Men could have up to four wives because, with all that war and massacring, there were a lot more women than men.
Largely female slave societies have been common throughout the world until modern times. It is only Judaeo Christian societies that have found a place for Man's energies without killing him or castrating him. At the same time Christian culture freed all women from slavery.
It was quite clear to our Christian ancestors that the men served the women. Only with the rise of atheism in the eighteenth century did the notion of male superiority begin to make inroads outside the warrior and bureaucratic elites.
Since then we have seen the collapse of Christian civilisation and its inevitable corollary - female servitude.
