Hi Tim,
I would have to say why should anyone need to be forced to pay child support? Child support is an obligation of the parent to their child, not the other parent. Whatever your or my or lenny's relationship might be to a mother, be it long -term, paid or a one night hook-up, the child is owed the support of both of its parents. One can choose to fight over support to the mother (or not), but there should be no thought of not meeting one's obligation to their child.
Let's look at this rationally and logicly.
Suppose i accidently impregnated a Vancouver SP & she carried it to birth. And this child was one i never wanted. I have no feelings for it any more than any other child on earth. Why should i? In fact i have more feelings for & feel more obligation to other people's children in poor countries where they are starving & do not have the Canadian welfare state to take care of them. I'd feel more obligation to children of SP's i see in 3rd world Thailand, children which are not mine, than i would to my child with the SP in welfare state Canada.
My child would be a product of two people, so i suppose it could be said it's biologicly 50% mine and 50% hers. Compare that to one of my BMs which is biologicly 100% mine. Just because something is biologicly mine, does not necessarily mean i have any moral, emotional or financial obligations to it. Although in the case of the child, as opposed to my latest piss in the toilet, it has needs. But so do millions of poor, starving or homeless children on earth. So why should the biologicly 50% (accidental unwanted) lenny baby get special treatment over other non lenny children who have greater needs? The greater obligation, if there is any at all, should be where there is the greater need, not based on biology. Besides, BTW, if we go back far enough in history, are not all humans related biologicly?
Canadian law obligates me legally to support my 50% biological (unwanted accidental) Canadian born child financially. Take that away and i have no obligations to the child in any way, whether morally, emotionally or financially. After all, she (the SP) is the one who chose to keep the child, not me. I might have more feelings for my dog that has lived with me for 10 years, or a starving homeless crying kitten.
