RE: If we were living in a male-dominated world (with links)
If men wanted to oppress women they'd be sent to wars as cannon fodder and make up %99 of the casualties to save the lives of the more precious male sex from such brutality and death.
The entire world would revolve around a "Men and children first" narrative. Humanitarian aids would constantly and only discriminate against women.
Men would create a movement to erase the female sex through eugenics (#theFutureisFemale) regularly call for a gendercide of women and call for it's action (#KillAllMen) and wouldn't be punished in the slightest for spreading those ideas. Men would openly associate with these ideas publicly knowing they won't be punished in the slightest.
Despite things like #KillallWomen, only sexism to men would be banned and punished, misogyny would be mocked, refused and denied to even exist by the men's rights movement.
Men's rights would victim-blame female suicide victims with toxic femininity and be obsessed with slut-shaming women and female virgins. Men's right would create loads of sexist terms like "womanspread, womansplain, bagsplain" to attack women for decades, including incessant sexist generalizations for decades. If any women objected to their insane sexism, they'd be attacked with fragile femininity and fragile egos. Oh yeah, and every single sexism the female gender faces would be gaslighted and victim-blamed onto women by calling it all "toxic femininity"
Be a man, and you're already experiencing every single thing written here and by OP. Yikes.
