That's because men and women, as groups have far greater vested interest in relatively peaceful resolution of their conflict, a way that that slaves and masters, as groups do not. The battle line is never clearly drawn.

I don't doubt that such slave rebellion fears existed, but equally, there generally was, akin to the mysogyny-internalised women that spaz refers to, plenty of slaves who had internalised their roles as slaves.

Given the keys to the manor, although dazed at first, would they still choose to remain slaves?
