Womansplaining

a non-word erroneously used as gendered equivalent to 'mansplaining' for a condescending woman.

A gendered word with a corresponding impact to 'mansplaining' does not exist.

MANSPLAINING contains an element that is often overlooked: It's the systemic cultural conviction embedded in societies that women cannot truly be competent, cannot be more competent than a man, and that her opinion carries less value.

Mansplaining is anchored in sexism.

It's part of the male entitlement that a man who has little to no expertise but a lot of 'opinion', often enough talks nonsense (sharing factually incorrect non-proven information), will be and IS taken seriously. Why? Because that has been the rule for centuries.

In 'WOMANSPLAINING' i.e. women being condescending to men, the element of power is missing:

Even though she condescends to him, neither he nor those in his environment will doubt his competence. Her condescension has no impact besides the personal.
With mansplaining, that's different as others are likely to buy-in and fundamentally question the woman's competence.

Thus, just like in racism, white people can and do experience discrimination but not racism because the systemic power element is missing for them, men can and do experience condescension from women but not 'womansplaining' because the repercussions on the perception of their competence is absent for men.

She was womansplaining to me.

No: She was condescending. I understand how annoying that is, but it is really not the same thing as mansplaining.
