As to the 3/5ths jibe, a person was not counted as 3/5ths because they were Black, only if they were a slave. A free person, regardless of race, was counted as 1 person for purposes of apportionment of political power. And a slave, regardless of race, was counted as 3/5ths.
And the tragedy is not that they counted as 3/5ths, but that they would be counted at all for apportionment of political power.
The Senator from a slave state DID NOT represent the interests of their slave constituents to the same degree that a Senator from a free state represented the interests of their free constituents.
There was no uproar when democrats posted pictures of Pres. Bush and a chimpanzee. Anyway, thanks for enlightening me and don't be ashamed to proclaim these scientific facts to your black friends.
