I don't forgive any of the trespasses of the South. But imagine an alternate history where the 3/5ths compromise didn't exist. The North would have been dominated by the South in every election, because slaves were a majority in a number of slave states. Obviously it's an impossible counterfactual run, but things probably would have been worse, not better. But maybe not. It's also possible that the situation would have gotten untenable more quickly, and the system would have fixed itself.
You mean one where the north said "you know fukkit it's been four years and you guys are assholes and this is a dumb idea so fuck off until you can come back with something reasonable?" The Revolutionary War lasted seven years. The Constitutional Convention was four years later. The 3/5ths rule was debated for a fuckin' month. Congress spent ten times as long on Benghazi as it did on how human Blacks are. Imagine an alternate history where the minority population of the South was treated to minority representation and fuckin' slavery ended up abolished without a fucking war.But imagine an alternate history where the 3/5ths compromise didn't exist.
