OK, I don't seem to be making myself clear, so I'll restart from the get-go.
Feel free to tell me where I'm wrong.

Slave states are just plain immoral. The fact that many nations accecpted
the immorality of slavery doesn't make it less immoral. Yes, the US was
part of that immoral group.

Slave states have sloooooooooow technological progress. Give the Romans a
couple of hundred years and they ought to build better buildings than the
Greeks. Big deal. No era in human history has learned as much and has had
as much technological progress as the era which commenced with the beginning
with the antislavery movement in the late 18th century. This movement was
part of a larger movement which believed all people are equal in God's eyes.
Am I wrong about any of that?

If I recall correctly the Confederacy's Virginia/Merrimac was a
technologically simple, hulking ironclad. The Union's Monitor had most of
the actual technological innovations, including a rotating turret. Am I
wrong about that, as well?
