OK, then you should be fine with men having the option of taking full custody of the child, if he so chooses, and having HER pay child support, under the full enforcement mechanisms of the state.
I have no problem with men “taking custody” of the child, None whatsoever.
But single parenthood is not the ideal no matter who the “custody” parent is. That is a Band-Aid solution at best. Better than abortion, sure. But we should aim higher than that.
