I didn’t claim otherwise. I did, however, point out that it might be useful to ponder the impact of Amendments and legislation passed with the aid of imposed, military occupation Reconstruction governments in the south.
Why?
Well, after Appomattox former Confederates were naturally forbidden to vote, while their former slaves did vote, resulting in the amendments & laws you reference.
So clearly & obviously those acts expressed the wills of voters at that time.
But what's even more "useful to ponder" is what happened after the election of 1876, when the old pre-war alliance of Southern slavers with Northern Big City immigrant bosses reestablished itself enough to allow Democrats to make important demands in exchange for supporting a Republican president.
What demands?
Well, essentially nullification of the 13th, 14th & 15th amendments for the next 100+ years and the rule of Black Laws, Jim Crow & KKK type enforcers.
Plus the teaching of fake history about the Civil War to generations of young minds throughout the South, resulting in some outrageous nonsense we see here.
