It’s right there in Article I of the Constitution — Black people are 3/5 of a person and Article IV mandates that states return fugitive slaves to their rightful owners. The Constitution is for all its glorious symbolism a manifesto of oppression — legalizing the ownership of humans per amount of melanin.
Have you ever considered reading up on the history of the 3/5 rule?
The 3/5 rule was proposed by those opposed to slavery, and not because they viewed the slaves as less than full human beings. The slaveowners, who did view the slaves as less than full human beings, would have preferred to have the slaves counted as full human beings.
This was not a matter of voting power, btw; the 3/5 rule had nothing to do with that; voting rights at the time were limited to landowners. This was all about Congressional representation.
Despite the 3/5 rule, the South still had a disproportionate political power:
The Three-Fifths Compromise gave a disproportionate representation of slave states in the House of Representatives relative to the voters in free states until the American Civil War. In 1793, for example, Southern slave states had 47 of the 105 members but would have had 33, had seats been assigned based on free populations. In 1812, slave states had 76 out of 143 instead of the 59 they would have had; in 1833, 98 out of 240 instead of 73. As a result, Southern states had disproportionate influence on the presidency, the speakership of the House, and the Supreme Court in the period prior to the Civil War. Along with this must be considered the number of slave and free states, which remained mostly equal until 1850, safeguarding the Southern bloc in the Senate as well as Electoral College votes.
Simply put; if not for the 3/5 rule, the South would have controlled the politics in the US entirely until Emancipation, and would have been able to postpone that emancipation, more than likely. The 3/5 compromise gave the North more power than they would have normally commanded based on free population alone, and thus accelerated the Lincoln (or somebody with his agenda) presidency.
And, if it weren’t for the 3/5 rule……there’s a very good chance that slavery would have lasted several decades longer before the political environment was able to oust it.
A study of the 3/5 rule is a very real illustration of why the old saying “Don’t Judge a Book by its Cover” is so very true.
