I think we focus so much on colonial slavery here because it's our history, part of our identity as a country. It's the original sin of the United States, as it were. Sure the ancient Egyptians and Romans owned slaves, but no one today claims to be the continuation of Egypt and Rome. Those civilizations are gone, we look at them objectively. We cannot look as colonial slavery the same way because we are the same country that once owned those slaves. We are grappling with that reality still to this day

What I don't get is why when it comes up it always comes up as the worst version of slavery to have ever existed- or as the only slavery to have existed in its time- or to have been much different from other slavery that existed either in its time or across history. 

We also don't look at those civilizations objectively. While self castigating over the slavery in our history we do have a tendency to whitewash the slavery of other places and times--- you can see it in this very series of replies I'm making. People point at stories that were so noteworthy to a largely illiterate people that they got written down and recorded for record as reasons why this cultures slavery was way better than the slavery were more familiar with. Using a story that we only know because it was worth recording and preserving 2,000 or 4,000 or 6,000 years ago. Sometimes when writing itself was considered a skilled labor
