I've had this going through my head for a while, but I couldn't quite articulate why I had this feeling that it shouldn't be taken at face value.
I think I worked it out. Women's groups are worried that their privileges will be on the chopping block and rolled out the most absurd thing they could in a desperate attempt to rally people behind defending them, on the day where everyone thinks about the most and usually only positive female influence they have in their lives.
It's a cheap trick, the typical appeal to emotion that they're so famous for. You're thinking of the woman that likely you have a deep connection to, so you think "I don't want her to be called a birthing person, she's my mother" and back whatever retarded bullshit Defending Female Privilege Bill 42069 contains.
It's called cognitive dissonance. You strain very hard to try to explain the massive amounts of evidence that women are outranked by Pakistanis/blacks and transvestites.
