Wait, I didn't read anything after the response to me.
Sarge, the anti-slavery advocates wanted the slaves to count for ZERO. 3/5 was no victory for them. It was a victory for the south. Any added population that inflated the white south's numbers is a victory for them, considering that it would have been right and just for them to get nothing extra. If you're supposed to get X amount of something, anything you get above X is spoils. And in turn, the north lost too, because their rightful proportionate share of the members of the House was reduced fraudulently. Any compromise on this matter should have been unacceptable to the North. I don't get why you think black slaves benefitted from any evil act that resulted in the slaveowners becoming more powerful than they deserved to be.
