This is why I rarely post on the abortion issue. I am strongly pro-choice. Like the pro-life Christians my stand on this issue is based on my faith. I believe it has to be a decision that can only be made by the woman, her doctor, and her [Choose one: rabbi, priest, pastor, etc...].
I'm strongly pro-choice too. And I'm sure the traditional orthodox Jewish teaching is that for the first 40 days after conception, the "product of conception" has no significance. I believe this is from the Talmud. When I've mentioned it to anti-choice orthodox Jews on FR, they've agreed that was the teaching, but they have rejected it on the grounds that "they just didn't know about the biology of reproduction back then". Odd, from my standpoint, that these same people still feel the need to adhere to dietary rules that were clearly based on limited knowledge of food-based infectious disease. Cafeteria-style orthodoxy, I guess.
