That's a misunderstanding of the intention of that provision. Back in the day slave owners had as many "votes" as they had slaves (the slaves themselves didn't vote), under the assumption they "cared for" those slaves and were representing them. This gave them immense political power.

To curb the power of slave owners the anti-slavery States managed to approve, against slave owners' interests, the rule their slaves didn't count as full votes. This way slave owners had less total votes, strengthening the abolitionist camp.

I did not missunderstand anything. I said the constitution was not created to grant equal rights to all people. I think your elaboration illustrates that clearly.
