This is the 'racism' that women have faced from the dawn of civilization. It seems to have been born from the early formation of tribal conflict. We have seen that hunter-gatherers functioned more equitably, even though women bore the children and had a higher burden. It seems that as agrarianism grew and allowed a higher population density, some degree of group impingement competition arose - which led to resource scarcity - and then to conflict. Men with their greater strength became more combative and role specialists emerged. I suspect this was the start. With a warrior class emerged the pushed around class.....the middle ages were bad, no vote at all for women in many societies, and not vote even for men with no land. By the 1600's this was solidified in many places. Gradually universal suffrage emerged after years of conflict. In Einstein's day women were severly abused in the way that Mileva was. This endures to this day, try as we do to eliminate it, these abuses persist all throughout society in many places. I agree, Mileva deserved far more credit than she got. That evil professor was one of many that infested the ranks of Academe. The ranks of higher education are still riddled with these abuses - every day we see more of them outed. Downgrading women is a HUGE burden to society and I do whatever I can to eliminate this is an my interactions.
