Then, by all means, do so. Just don't ask the Federal Government to pay for it!
The liberal doesn't care about stem cell research so much as she loves the idea that killing her baby will make superman fly again.
She will not only be free of guilt but will feel that she did a great service to mankind. It only works when the government contributes something because the government is "all of us"...therefore the killing of her child is praised universally.
It doesn't matter what the abortionist actually does with the child afterward, he just needs to tell the mother "this selfless act you have done today will give a new lease on life to a suffering person somewhere"...guilt free abortion.
