Slave men
Men, because they can't generate new life as women can, are only valuable to the extent that they will work and be good at their work. Therefore, there is a difference in the community between the treatment of men and women.
Slave women
In slave communities, women often depended on each other greatly, driven together by their shared experience as both "slave birthing machines," and as labor slaves. The reason they were treated as slave makers is because slave owners could impregnate their slave women to make new slaves that they could sell for money or exploit on their land.
Slave owners
In America, the laws used to be such that white men could own other human beings as property, and so many land owners built entire empires on the backs of their African slaves.
Slave traders
A woman was more likely to be targeted by a slave trader (kidnapper) if she seemed likely to be able to both work and bear children, meaning that women of old age were often not useful for those purposes, so women of relative youth, health and attractiveness become the most vulnerable to these traders.
