You couldn't be further from wrong. Doe simply stated that if there was an exception what it had to include. It did not state that there had to be an exception. You are trying to argue that the justices made one ruling and then said, "nah just kidding" in the next.
The ban without an exemption was upheld.
But that's exactly what they did, because we have abortions up to the 8th month... no restrictions.
The big problem was when the Court passed Roe and Doe in 1973, they really didn't think it was going to be controversial.
They thought they were getting rid of dumb laws no one was following at that point, anyway. Which is why FIVE Republican justices joined 2 Democrats in striking down these laws
Little did they suspect the Evangelicals needed a bullshit issue to get the stupids to vote against their own economic interests.
