The 13th and 14th were in direct response to Dred Scott, more specifically, the 14th and did in fact negate SCOTUS on Dred Scott.
A Constitutional Amendment defining marriage as 1 biological man and 1 biological woman would also void SCTUS’s homo ruling.
So would packing the court with six new right wing judges and reversing the current bunch of homos.
Lot easier than an Amendment.
Nothing in the Constitution that says there has to be nine members of the SCOTUS.
