I think you are actually bringing up a fair point for once. I'd agree that if abortion were 100% legal and easily accessible, the man should not be held liable in this situation where the woman wants the child and the man does not. We are not at this point yet, however. I'd also add that if an abortion was instead the choice in this more ideal world, the man should be expected to help pay for the costs involved there. I think that's a more than fair trade-off for removing the forced payments for the raising of a child.
I don't believe you. Get over it.
