Not OP but probably because it's prudent not to ignore the obvious gender differences. Promoting gender neutral views surrounding situations that are very gender relevant is willful ignorance.
Not for any single reason. There's the law of the excluded middle, a principle from logic. There is evolutionary thinking. There are anecdotal accounts of transexuals of the difference in sex drive. There's the physical size and strength differential. There is the historical thing of protecting women. I take all of these into account and try to form some sort of guess of what is likely.
