One can make an argument for abortion rights under Roe vs. Wade. The argument might not be persuasive, but there is a certain logic to it.
The argument for Embryonic Stem Cell Research, on the other hand, is flat-out evil. It weighs the value of human life against some external good, and finds in favor of the external. That kind of utilitarian thinking has paved the way for every mass-murdering despot to come down the pike, from Cain to Hitler to Mao.
We know where this road leads. We must not take this turn.
Only if you ignore the issue of whether or not an unborn child has rights of its own, and focus solely on the right to privacy of the mother, which the court did.
Aborting a fetus is murder.
Abortion should only be legalized for rape, incest or the endangerment of the life of the mother.
Abortion should not be used as a birth control method.
