Do you have balls for that?
If you have any doubt our culture is a patriarchy, you have 5 seconds (that's how long it took me to come up with those phrases) to type 3 phrases with the exact same meaning in common use that articulate the female in the exact same way.
I'll save you some time. You couldn't do that if I gave you 5 days. There are none.
Think about that for a second. It's women who regularly push something the size of a watermelon through a hole the size of a lemon, but you need testicles to be brave.
It's women who raise the majority of children after divorce or breakup, by themselves, often with little or no help, but acting like an adult is masculine.
Women still, after all this time, make less than men and do more housework and shoulder more of the child rearing responsibilities, but we need to "cowboy up" not "mommy up".
Throw like a girl.
Scream like a girl.
Cry like a bitch.
It only took me 3 seconds to come up with those. Go ahead, you have eternity to come up with three phrases in common usage to express the exact same level of deliberate contempt, only using the masculine as the shaming device.
Go ahead, get back to me when you give up.
It's okay, I'm just a feminist with no sense of humor. It's not that you're not funny. And the patriarchy, it's fucking delicious.
