One of the books that helped me understand this is a book written by Evan Bernick and Randy Barnett, "The Original Meaning of the Fourteenth Amendment." US v Cruikshank: Want the privileges and immunities clause disabled so Blacks can't avail themselves of the protection of the law? No problem.
Pierson v Ray: Want to make it so Blacks can't sue judges and police officers like the KKK Act(s) say you can? No problem. Castle Rock v Gonzales: Want to re-write the Equal Protection Clause to mean police have to provide Blacks with the same protection as whites? No problem. And on and on...
Endless examples!
