I think once you see how much damage colonization did it’s easy to blame everything on that one evil. But that’s oversimplifying to an extreme extent.
For example, I really doubt the idea of class based karma (or karma based class perhaps) was a colonial introduction to India. I’m not disagreeing with you that modern capitalism is bad or saying that colonialism wasn’t damaging, those are both true, but it’s pretty damn patronizing to says “they couldn’t have had bad socioeconomic practices without us” Hell they had a literal caste system of worker exploitation long before we showed up.
Presidential pardons are one of those incredibly stupid things that show in the end America just wants a king.
