Wars kill some innocents. Embryonic stem cell harvesting kills all innocents. There are alternatives for harvesting embryonic stem cells from placenta and umbilical cords, not to mention using the far more successful adult stem cell research.
If you want to invest in embryonic stem cell research, you can do so through the private sector which can do all the research it wants if its willing to fund it. Taxpayers don't need to be doing what is private sector work.
Some or all...sounds like the killing of innocents is relative.
But they did when it was adult stem cells. The work you cite as succesful started back in the 1960s with government grants at universities. Only now is it maturing to the point that private companies are willing to look into the ROI.
Asking companies to take on a 40-year project means it will get nowhere. It was the same with the space program, but now we are seeing the economic payoffs of government funded space exploration.
Sometimes government does need to step up and spend money to push innovation.
Embryonic stem cell harvesting kills all innocents.
Those poor little innocent blobs of proteinic goo.
