Here's something to think about:
On last night's edition of Politically Incorrect (for 9/9/99), one of the panelists named Melanie Bysouth (IIRC) revealed one of her radical feminists proposals. She said that men who sire children out of wedlock should not be held legally or financially responsible for the children they produced. Her reason was that women have the choice to not participate in acts that would have this result and that they are reponsible for their own bodies and men shouldn't be.
I want to emphasize that this is not my idea and that this was presented by a young woman claiming to be a feminist. I am not offering my opinion because I'm not sure I've actually come to one and I'm curious to what others may think about this (and let's just say that most of the audience and panel didn't take too kindly to this idea).
