It's bullshit.
If that were anywhere close to true, only women of child bearing age without children would be advocating for social justice.
Look around.
Does that appear to be the case for you?
If that theory were anywhere near true, there would have been no social justice prior to the development of the birth control pill.
Did you both flunk out of history? Ever been to a museum? Fuck's sake. Have you read your Bible? Don't you go to church every week where they tell you all about Jesus' life? What did you think all of that was about? I mean, you certainly tell us all about your cliquish church groups enough. Is that ALL you're getting out of going? Then why go?
For real, what is with you men? Can you not stop this dumping on women about everything under the sun. Especially "interesting theories" that 2 seconds of common sense would show to be abject nonsense.
Again. Ted. Edit --for crying out loud. That red pen is your friend.
