Mmm. I think the problem with that viewpoint - and in fact the way the entire RF is forced to live - is that familial relationships, particularly parent and child, should supersede all matters of state. If that isn't the case, you end up with human beings being treated as collateral damage.
KC's recent ill health has possibly reminded him of this. I am sure those of us who are mothers can identify with the battle not to allow our professional lives to over-ride our personal relationships with our DC.
And as so many people on here keep pointing out, Harry has never rejected the institution of the monarchy. His beef I believe is with the way it's run by the men in grey suits and the way he and his wife were treated within the Firm, and that's a position I have a lot of sympathy with. I don't necessarily agree with the way he handled it mind you, but I believe he was justified in some areas.
Also, if you push people in to corners and their pride is hurt, and you effectively humiliate them in front of their new wife, and you leave them with no face-saving alternatives, they are bound to bite back. It was all handled terribly.
Also, I think we can agree that if Charles and Wills can manage a reconciliation, whatever their personal thoughts on the matter, but if they can all behave professionally, including Harry, that can only strengthen the monarchy going forward.
I am a republican so I don't really care one way or another, but in terms of normal family relations, of course it's better if there can be forgiveness going both ways.
