And there goes any argument about 'best interests of the child'. Men are completely free to give up their parental rights, if they don't want to be responsible for their children's financial support. And they do it all the time.<quoted text>
You also don't have men caterwauling about how it's their decision and their decision alone. Yet you expect that others should pay for it. IF the choice is yours and yours alone as you claim, then so should be the financial responsibility.
Men have no legal responsibility for a pregnancy. None. Only for their born kids.
Men are as free to refrain from sex, as women are.
If you don't want to be held responsible for your born kids, don't get anybody pregnant.
