> This has been used to deny women entrance to universities, to take out loans, to own property, vote, participate in politics, make laws, start companies, become scientists and doctors, run marathons, and make many substantial decisions about their lives. If these differences weren't historically used as justification to deny people the ability to have control over their lives, then yes it would be easier to talk about them.

Correct me if I'm wrong but a majority of men throughout history did not have many rights either. 'Rights' were enjoyed by a few male aristocrats. History is written and perpetuated by the aristocrats. Note that rights were not that important for life quality for commoners in the past when people were struggling through wars, famine and lack of basic technology.

Men also have had massive disadvantages because of the differences. Compared to female 'disadvantages', male disadvantages had higher impact on life quality and were less likely to have an intersection with commoners of the other gender. The male disadvantages being: dangerous physical labor jobs, participating in wars, less likely to start a family, forced to be the breadwinner and work at remote places away from family.
