@chrisjrn To put it a different way: it always feels to me like absolution, not awareness-raising. “I don’t have to do anything more, I gave an acknowledgment!”
It is possible I’d feel differently If I’d seen even a single one that had a link to a concrete, specific plan of restitution. Could be anything: National Park transfers, seats in Congress, etc. But that would force people to grapple with actual action, and no institution will admit to that as a goal.
