There are arguments made by some religions and cultures that any form of contraception is morally wrong. It doesn't even have to be after conception. The Catholic Church, for example, is against condoms.
At the other extreme, there have been cultures that practiced infanticide -- such as Sparta and, more recently, in China (girls).
The line has been drawn from before conception to after a live birth. This question has been with Man probably since the beginning. Even if Roe is overturned, it will not end the debate -- or the struggle over what the Law should say in this matter.
I don't advocate stopping contraception. I just want everyone to be honest about the whole conception thing.
