Embryonic stem cell research kills life. It is completely different then any other type of medical research out there.It seems that the only way one can be opposed to embryonic stem cell research is to simultaneously oppose IVF, which pretty much kills the "I have more regard for human life than you do" argument. I'm not making fun of your argument by any means, but I am understandably curious.
Also, can you be for IVF, then complain about overpopulation? That one has always perplexed me.
