I would probably agree that the Justices hoped that Roe would be no more controversial than Griswold was. They failed to account for how the Evangelical Crazies would glom onto Abortion after Segregation stopped being a popular issue with their congregations. (Before Roe, the Evangelicals saw abortion as a "Catholic" thing, and the Catholics considered abortion somewhere long the lines of "using contraception" and "Eating meat on Friday during Lent" kind of sin.)
No, guy, Roe isn't as "Bad" as Plessey. Roe was pragmatic because by 1973, most OB/GYNs were ignoring abortion laws and performing abortions in their offices.
The reality of the pre-Roe abortion laws are they were rarely enforced, as opposed to segregation, which was actively enforced. (That's what made what Rosa Parks did so radical).
Abortion providers were only prosecuted if they got sloppy and injured or killed the woman. Women were almost never arrested for having abortions.
The only thing worse than a dumb law is trying to enforce a dumb law. (As we are seeing now with immigration.)
