If we assert that Abortion is a choice of the mother, in order to make it logically equal it would be her choice whether to carry the baby or not but it should be the father's choice whether to support it or not as well.
If the father can be forced to pay for the baby even though he wished for it to be aborted, then the mother should not have the right to end a pregnancy if the father should wish to care for the child. Since the Mother does have a legal right to the choice of carrying the child, and she can force the Father to pay regardless of his feelings about the child all of the "rights" in those cases are lopsided and against males on a whole.
