Stem Cells to stimulate growth of common sense?

Interestingly enough, I happened upon an encouraging article about the use of patient skin cells to grow liver cells.  Quite a promising development indeed, and to be celebrated.  But why is one of the first comments about this technology's promise that it can avoid the controversial human stem cell debate in the US? Breakthroughs can, should, and will come from a variety of sources - and IMHO one of those sources should be stem cells.

If you disagree with the use of stem cells, don't have a procedure using them.  But for heaven's sake (pun intended) don't stop others from keeping innovation, and better health moving forward.
