Demonizing the male gender is a new phenomenon. Throughout history, the female gender was way more demonized.

Notice how in religions it's usually women that are the cause of all evil, from Eve to Pandora.

Various religious leaders also demonized women. Muhammad supported the notion that women comprise the bulk of the inhabitants of Hell and said various other things about how women's "wickedness is contagious" etc. etc. In hinduism there is a religious epic that describes women as "impure by their very birth, they blight all virtues, their nature is to be vicious, fickle and sharp-tongued." In Christianity, Tertullian had said that "every women is an Eve". Saint Clement of Alexandria had said that women's own nature should evoke feelings of shame. In Greece they used to say fire, sea and woman are the three evils.

In general why do you think women used to be singled out as the "evil gender" before feminism?
