>>29 wow, glad to see someone posting on the stem cell debate again. (^-^). I have to ask though, how do we really know if in the future "designer babies" won't be developed for vanity purposes? Sure, I see how germline therapy could help treat genetic diseases in offspring, but it could also be used to permanently alter a family's genome too. So, if a mistake were made, that mistake would continue on through future generations in that family. Get what I'm saying? So how would we guarantee that "mistakes" like that wouldn't happen to people if embryonic stem cell therapy is authorized? It's not as though we can test out germline therapy on actual humans--it's too dangerous and challenges human ethics far beyond its limits.
