While undoing the Iraq War because we later discover part of the reasoning we used to attack their country is not really possible—given the extreme disruption we have generated by the appropriate removal of a tyranny and the honorable work to build a democratic state—we are under no such restriction in undoing Roe vs Wade if we discover that the reasoning that was used to justify that judicial ruling was based on false premises.
A new book Dispelling the Myths of Abortion History, has discovered the flaw—the very serious flaw—in the reasoning and, hopefully, it will play a role in the eventual over-turning of Roe vs Wade.
This is an excellent review of the 2006 book.
