Wing nuts are upset because it is now possible to make sperm and eggs out of stem cells. This could provide people who no longer have functioning gonads the opportunity to be parents.
What would be really cool is if they learn how to make eggs out of sperm and sperm out of eggs. Then a person could have children who, while genetically different from the parent, would only have one parent.
That's the ultimate ego trip. Man, I'd want hundreds of kids to inflict on the World.
