True, the British monarchy are not the Kims.... but 400 years ago they were exactly that. We gradually reduced their power, and we only had to kill one of them to do it.
If an institution doesn't have equity of access and is funded by the taxpayer, I would want to know why. That is also true of all black institutions if there is no ability for anyone from any other race to become involved then it needs to justify the prejudice and I'd be concerned about any such institution being adjacent to a pluralistic government.
