No, it was a rogue court in 1973 that opened the door to abortion.
Explain why states had their own laws on the books then?
Texas legislators put a law on the books that treated unborn persons as much less than other persons. Which the Blackmun court used as a pretext for treating them as less than a human person, with the protections of the Fifth and the Fourteenth Amendment that involves.
Which is why I posted earlier:
“It was legislative exceptions to equal protection of the supreme God-given, unalienable right of the individual person that opened the door to abortion on demand, and it is exceptions that keep that hellish wide door open to this day.”
-- Justice Harry A. Blackmun, Roe vs. Wade, 1973
The only question that matters, constitutionally, is:
Is the unborn child a person, or not?
I say it is self-evident that they are.
Blackmun said "no," while admitting that if they are, they are protected by the Constitution.
What say you?
