Thats very feminist of you.
Sorry but he is still the father. It may be a bad father but still the father despite your derision.
These women do not realize that men don't want to raise some other man's mistakes. Fatherhood is not a fungible comodity.
Oh, and by your reasoning, you just condemned every man who has ever remarried a woman with children. There are plenty of good examples, even on this thread, of men who've stepped up to the plate and been a father to children who are not theirs biologically. Yes, there are even married couples who have to use donor sperm- yet the husband still raises the child as his own.
I bet you'd call a women who rejected a man's children (by your example) a b!tch.
Yep, if I'm a feminist, then you're a Neanderthal.
