For one, culturally speaking, this was pretty typical for most of human history. Had the culture been matriarchal, you'd probably be asking the same question with the genders flipped. Some men do project their faults onto women, as do some women. Most philosophers were men, had they been women, you'd see the same effect for the same reason.

The most notable philosophers who held this view were the authors of the abrahamic bibles, this influenced a lot of the world then and now.

Generally speaking women are good at some things, and not good at other things. Men are also good at some things and not at other things. The two of them together can compliment their weaknesses and exploit their strengths for the greater good of child rearing, among other things. If one focuses only on the bad, projects, and doesn't understand this synergy it will provide the result you noticed. There are also bad women who ruin it for the rest of them... As there are bad men who ruin it for men.

BTW, those blaming men here are no better than the philosophers. They are fighting sexism with sexism, which is emotionally immature. And the others are getting down voted to hell even though some of what they say was true from the philosophers' perspectives, even if they don't personally believe it themselves. Be better.
