Well that's because girls are raised to be fragile and manipulative in that way, and society plays along and not only lets them get away with it, but encourages it in all but name. Men are taught and expected to sacrifice their whole existence for the so-called "greater good", aka blind loyalty to human society.

As a result, many women become both extraordinarily timid, weak, unconfident, selfish and expert manipulators without even realizing it, with no bad intentions; moreover, they see themselves as weak and incapable, both a justification for demanding everything from others and discouraging them from independence and innovations, or even attempting a challenge. And men become unthinking unfeeling drones, which keeps them also from questioning the status quo. Then they each vote for politicians and leaders who suit these personalities.
