I am unwilling to let this thread become a discussion about the wisdom of using contraceptives. I will not pursue why you decided to raise the issue in this context.
Your assertion, however, that the Pill has been the primary engine for recent social changes is false. Women made the choice to use contraception. A closer examination should be made as to why those choices were made.
So, I think if you want to unwind all of these changes, you're going to need to eliminate the freedom that women enjoy because of birth control devices.
Freedom is very odd word to describe the effects of the Pill on women.
Well, like you say, "Women made the choice to use contraception." ;-)
