It's easy to grandstand when you aren't faced with the decision. The reason I know about the vaccines and their derivation was because I was on a message board once where a very religious social conservative said that he would never, ever, ever, allow his infant son to be vaccinated for chickenpox, because of the vaccine's derivation back in the 1960s.
Well, he at least had the honesty to report back that the kid HAD been vaccinated, because his wife and his mother both said, "You're nuts!" and got the kid vaccinated. He caved in about five minutes.
You can get that right here on FR; on a stem cell thread a LONG time ago, I mentioned that my sister, who had ovarian caner, had had stem cell replacement.
Before I could explain that they were her OWN stem cells, one of lovely "real conservatives" on here posted back to me that my sister had lived long enough and didn't need a fetus' stem cells.
*Sigh *
