Something like 2% of Americans owned slaves.

The very nature of a slave system is such that everyone who isn't enslaved benefits from slavery 

I do dig most of your thinking though- I hardly think it's fair to judge any past society by today's metrics, because under scrutiny they would all fail the moral test. It's best to compare them to others if their times, where they came from and where they went 


I also think you might take interest in some of the private correspondences of some of the founding fathers of America, specifically where their private statements and public positions were mutually exclusive on the topic of slavery. There's a couple of letters and names are escaping me hard right now where one of them is actually talking to someone about how they can't propose abolition even though they support it because the people they represent would lose their shit if they did (not hero worship or using today's standard---- i certainly found it interesting to read their own words about how they seemed to feel stuck between a rock and a hard place on this very issue) 

I apologize if I've messed up grammar or left thoughts half formed- I am very tired

I made it clear that I referred to southern states. The 2% number of as for all of the 33 states, where slavery is as illegal in 18 states. Only counting the slave states, the percentage of slave owners in the 1860 census was 4.75% of the free population. Those 4.75% were men, and they had wives and children. That puts the number of people who had the food on their table put there by slaves was closer to 20-25% or more, making it highly unlikely that none of a southerner’s ancestors were from a slave owning family. 

The 1800’s is close enough that it feels like people shouldn’t be that different from today. I was born in the early 1980’s and I have let people born i. The 1800’s. I have met people who had met people who were alive when slavery was legal in the US. Be it fair or not, I think that’s why people wonder how people back them couldn’t see the error of their ways. It’s so close, yet also so very distant. 

Regarding the letters and personal feelings of the founding rapist torturers of the USA: would you make excuses for a Nazi concentration camp guard who wrote a letter about feeling a bit stuck in the murder machine? The torture and scale of murder was higher in the 1940’s than in the 1840’s, but a somewhat guilty conscience doesn’t absolve anyone of responsibility.
