I agree and disagree at the same time.
In that, it doesn't look like the monarchy will be going away any time soon. So for me, I don't think any of them should just walk away. I think the palace needs radical reform to work kindly and well with the family within. They are not doing that, currently. The institution is treating the family appallingly, afaics.
Saying, they can just go then. To me, sorry, but it sounds very much like a poc complaining about institutional racism and telling them 'just go then'.
I am not a republican in particular. I was a child and loved Diana with her glamour, beauty and empathy. Like most people I was bereft at her death. I lost interest in RF, but obviously still kept up with news, history etc. They were part of the furniture.
Over the years, I have not been happy with certain conduct of political and financial interference / peado associations / corruption etc. and never will be. But, I have to say, the blatant racism and white supremacy on top of this, is the straw that breaks the camel's back. If none of this changes, me and a lot of people I know, will put our full back into a republic.
