Your point it taken. I think you and I are in agreement with regards with all of this. I personally know childless women who have an enormous capacity for love. They're Gen-Xers like me and the chose not to have children. To achieve a more balanced view of gender I agree we have to abandon this kind of thinking.
Me? I'm still married with children. So, no I haven't been discarded :). Thanks for your kindness. If my wife ever divorces me or visa-versa, I will still be expected to be a father and co-parent with her. I expect this from myself. Additionally my family, friends and colleagues would find anything less as unacceptable. I would be ostracized until I resumed my responsibilities. I do realize that my social circle is not representative of society as a whole.
Moreover, my children are important to me. I couldn't just leave.
