Ummmm, their fathers released their sperm into a cup for chump change....I think they knew they wouldn't know their biological children. The point, which I believe you miss is this: Moms created kids on purpose without fathers. That's incredibly wrong and selfish. The fathers created kids without ever intending to love them, to care for them, or to raise them. That's incredibly wrong and selfish.
Do you think it's easy to go through childbirth and raise kids....of course the mom's wanted the kids. I was raised by my Mom...Dad was a biker, Mom left him. You think maybe my Mom should have given me up for adoption?
