I'm not accusing anyone, nor even implying that you would support Nazi experimentation, but you asked if I thought there were any benefit in embryonic research, and that was an obvious, if extreme comparison. I'm sorry if I didn't make it clear that there was no accusation of you in my reply. (I see why you thought there was).
My point was, that it doesn't really matter, since there is a higher value than the results of the research, and that is the sanctity of the life that it snuffs out.
