I hate this debate. The people who are against it are usually scientifically misguided. Stem cell research involves working on human blastocysts. BLASTOCYSTS. In other words, an organism made up of about 100 cells with no brain which means no neurons which means no pain receptors which means it CAN NOT FEEL. People will go "OMG you can't do that, it's like murder!" Murder my ass! That blastocyst feels about as much pain as the mashed potatos my little cousin splattered against the wall.
