1. Adult (including umbilical cord) stem cell research has resulted in over SIX DOZEN breakthroughs and cures.
2. Human life is destroyed to create embryonic stem cells.
Another non-sequitur. Research is not, and should not be, confined to any one direction.
That is the *fact* that I think is most relevant. It is, IMO, unconscionable that we direct so much money to a so-far failed theory (ESC research) instead of directing it toward a field that has been very successful and could do much more.
False comparison
The technology to harvest adult stem cells has been around since the 1960's while the ability to harvest embryonic stem cells has been around only since 1998. So you are comparing 40 year old technology to technology less than a decade old.
An analogy to your argument would be in 1936 saying we shouldn't research jet engines because we have dozens of examples of working propeller driven airplanes
2. Human life is destroyed to create embryonic stem cells.
And if they are not used for research they are thrown in the garbage as medical waste, so we might as well get some use out of them
