To be clear disenfranchising women (or etc., I don’t know all the letters…sorry) and slavery = BAD!
That said, I don’t know if these two items could be considered values, or just the way things were at the time. Contemporaneous writings at the time of the writing indicate that the inclusion of the 3/5 thing was abhorrent to many but a compromise that allowed colonies whose economy depended on slavery to convince their citizens to get on board.
Not directed @jswilson64 (I get you well enough from your postings to know you don’t need to be told this), but when people, especially young ones needing to be deprogrammed from 4 years of college, start going on about “America was founded on slavery!”, I ask them “quick, name all the countries in the history of the world that went to war with themselves to abolish slavery? Quick!!”
The saveable ones come up with the right answer…just one. The truly lost, sadly, can’t even come up with that one.
There’s a reason why the phrase in the Preamble (do you and you kids have it memorized?) is “more perfect union”, as in always trying to be better (although maybe not always doing too great a job of it on sme days).
That’s an American value.
