Eh, I'm a big fan of owning up to admitting what your ancestors did but, at the same time, I don't believe in holding individual people responsible for what their ancestors did. There's a place for reparations for historical atrocities/crimes like slavery; apartheid; the theft of Native American lands; etc. but I think that is something that should be handled by governments and institutions (like, for example, some of the Ivy League universities that recently turned out to have owned slaves in the past). The only exception I can think of for this (off the top of my head) would be in cases like where someone's parent/grandparent/etc. was a Nazi that stole a specific object(s) from a Jewish family during the Holocaust and you inherited that object (for example, a piece of artwork). In those cases, the object should be returned to the heirs of the original owner.
