"In slurring S. Africa, you slur early America."
The United States is 1789 was not a democracy.
and some enlightened Americans recognized that. But now its two centuries later and standards have (correctly) evolved.
Would you justify Islamic law executing Christian converts by pointing to similar wrongs done by Christians centuries ago?
Thank God, it still isn't. Its a Democratic Republic. But your obvious disdain of what my ancestors created is clear enough.
and some enlightened Americans recognized that.
So the Founding Fathers were "unenlightened"?
But now its two centuries later and standards have (correctly) evolved.
The "correctly" part is your own subjective judgement. There is nothing inherently wrong with how the US was originally constituted. A free people has the right to define their own form of government for themselves.

The execution of Christians for profession of the faith, from an objective view of Christianity being Truth, is always wrong and unjustifiable. From a realistic view, converts in the Muslim world should anticipate this fate, and offer their blood as seed food for the Church, just as the martyrs of Rome did.
The execution of heretics by medieval Christian authorities is an entirely different matter, since it was a matter of capital punishment for a species of treason and renunciation of oaths.
