I don't remember if he actually used "embryonic" stem cell research. You can used just stem cells that are not "embryonic". Maybe that's what Michael was referring to? Or not. Someone please correct me if I'm wrong.
Non-embryonic stem cell research is not controversial and receives a lot of federal funding. Michael J. Fox is talking specifically about fetal stem cell research, whether he uses the word or not.
Liberals like to confuse the two so they can wrap conservative’s objections to fetal stem cell research (which has produced not a single treatment for anything) with the perfectly acceptable (and currently productive) use of adult stem cells for treatment.
Embryonic, non embryonic, lab-grown or harvested; it still amounts to walking around the camel's nose.
