Worse than Roger B. Taney? His decision in the Dred Scott case denied any path to US citizenship for freed slaves. This led to the XIV Amendment to the Constitution and millions of anchor babies from China, Mexico, Haiti and a lot of other 3rd world countries.
I'm pretty sure his statements were just Dicta and not holdings in the ruling.
The holding that Dred Scott remained a slave and was not freed as a consequence of time he spent in a free state, is correct.
And I have only recently learned that the entire case was intentionally created by activists just to challenge the law.
This led to the XIV Amendment to the Constitution and millions of anchor babies from China, Mexico, Haiti and a lot of other 3rd world countries.
And I wish to point out that the 14th amendment would not have been ratified without puppet governments controlling the Southern states.
The 11 Southern states were effectively proxies for the DC government, and were not actually independent states at the time.
No amendments should have been allowed to be voted on by them while they were still under Federal occupation. They did not have legitimate governments elected by their citizens.
