Was this the same show where Whoopi Goldberg claimed that strict constitutionalist SC judges would bring back slavery?
They would except for the 13th amendment.
They wouldn't, states were
allowed to have slavery as part of their sovereign rights under the original document, it wasn't
mandated by the Constitution.
Worst case if the 13th went away would be... no effect. If the state laws then allowing slavery haven't been rescinded by now, they would be in an instant. States admitted since the 13th already bar the practice.
Remember, the Feds getting out of the way doesn't mean most things would immediately be legal or illegal, it just means the states would be free to decide again per their citizen's beliefs.
Abortion access wouldn't disappear overnight, as a majority of polled voters support allowing it in the cases of life of mother, rape and incest. Their state laws do and would reflect that.
Similarly for most equal protection issues.
