That's a lot of words to expend basically reinforcing my original point (and refuting a claim that I never made... obviously slaveowners tended to consider slaves lives as far less than three fifths of a non-slave except when it came to inflating their voting power in Congress) Of course it was a compromise and sometimes compromise renders evils necessary, but codifying the existence of slaves into the constitution obviously made the high ideals spoken of in the preamble look more than a little insincere, and the three fifths clause explicitly granted power to the slaveholders over the more sensible alternative weighting system for Congressional Representatives (number of voters/adults/free people) campaigned for by abolitionists at the time. If we're comparing the US Constitution to other constitutions written under their own unique pressures, its a clear case of the US Constitution not being drafted with more commitment to equality under the law. The fact that it was ultimately rectified after a war which killed 1 in 50 Americans isn't a particularly strong argument in favour of it being an effective compromise either.
