Good example set by the Dutch King. My issue with reparations is in line with Reisser's line. Who pays them? Certainly not the main benefactors the slave trade. And more importantly, who benefits from them? Probably not the people struggling most due to the damage.
If you were to take a far easier example of the Great Famine, I absolutely think the British government and / or monarchy should acknowledge the genocide they committed here, it'd go a long way in relations between the two. But firstly, it's not today's tax player's burden to pay reparations even if the British government benefitted massively from the cheap importation of food at the time and subsequent reduction in the population of Ireland. Secondly, where would the money go? Certainly not to the areas of Ireland where underpopulation is a massive issue, it goes into tech, finance, property etc... and maybe some culture but even then, the damage is done, acknowledging it, showing regret or remorse, and moving on shouldn't be scoffed at.
