I asked you a question. You did not answer, which makes you seem like you are trying to avoid the question because you know you are wrong. Unless you truly believe it would have been "a much better world" for the millions of slaves. Based on your other posts, I would be a bit surprised if that were the case. Which is why I thought we could just short circuit this whole debate by you admitting you were wrong. You decided to double down on not answering the question and make Trumpian personal attacks, which I'm not going to engage.
That doesn't work either. You are playing games like Fish used to you. How'd that work out for him?
But we'll do it your way just this once:
1. It is unclear that there would have been slavery in the South longer had we told the South to take a hike during the Constitutional Convention and gone our own way. In the event there was slavery for 70 more years. That's a pretty high bar for human misery. To quote your rhetorical tricks, surely you aren't minimizing all that suffering? My god, man, you're not saying you don't care about those years and all those millions? What is wrong with you; are you a sociopath?! ANSWER THE QUESTION OR YOU ARE ADMITTING YOU WERE WRONG!!!
See? That childish game is really easy.
2. Indeed I posited 2 possible paths where slavery ends in the South even sooner if we excrete them:
2a. Without the North the South may have had to develop an integrated industrial-commercial economy earlier, and slavery dies naturally, just as it did in the North and in Britain. It wasn't as if that was magic, or that the North was ethically superior. Slavery just didn't make business sense in a modern economy. By keeping the South we sheltered and subsidized their slave holders allowing them to hold on longer.
2b. As a loose confederation of nation states, without the central government ensured by the Constitution, the South may have fragmented into a chaos of failed states which the US then would mop up, eradicating slavery in each state as it did.
In conclusion, you'll never be a historian, an economist, or a debater, but the world needs conservatives to ditch dig too.
