Voting rights and slavery are easy things to pick on from our vantage point looking back 2 plus centuries.
They're easy things to pick on from any one who values the idea that 'all men are created equal'.
And given that slavery in particular almost destroyed the country, its rather easy to pick on historically.
In the context of the late 1700s where slavery and male dominance was the "norm", not right but the norm, I have to cut them some slack on those issues. I'm talking about the design and framing of the document itself and how well it has worked as the foundation for our laws and government.
White male land owning dominance. Kind of a rather small subset of 'all men', dontcha think? Especially when millions of those 'all men' were property with no rights. The horrid, loathsome hypocrisy of it was not lost on many of the founders either.
We've corrected many of the fatal flaws of the constitution, aligning its practice with its lofty ideals. And we paid dearly for the constitution's original flaws.
Oh, and you never did mention the Bill of Rights not applying to the States. Talk about an utter clusterfuck. The founders assumptions on the role of the states was laughably wrong. The States were not the protectors of the rights of the people. They were the prime violators of the rights of the people.
