LOL, what complete bollocks.
Harry is the son of a King and will always be the son of a King, and eventually the brother of a King. He is a BLOOD royal, that can't be taken away. He was born a royal and he will die a royal and there's absolutely nothing the haters can do about it which is why they're so triggered.
They have the power to remove all of his titles which he trades on so heavily.
Nobody outside the UK and even most people in the UK know or care about the intricate details of British heraldry. The whole world called Diana "Princess Diana" until the day she died but she never held that title or was even allowed to be called that. Didn't make a jot of difference. Harry could be stripped of his titles tomorrow, the world would go on calling him Prince Harry. Hardly anyone calls Meghan "the Duchess of Sussex" but being known by her maiden name hasn't affected her fame.
They already voluntarily stopped using their HRHs. Hasn't affected their fame or careers a bit.
Realistically the RF are not going to strip titles from a monarch's child since it would create a dangerous precedent, and also make them look petty and vindictive, and also make Charles look like he can't even get his own family under control. Edward VIII abdicated and he was a Nazi sympathiser, and he didn't have his titles stripped. Do you know how terrible it would make the BRF look if they decided to let a Nazi abdicator keep his titles, but took them from someone whose only crime was to marry a black woman and whine a bit?
They have the power to take Frogmore back.
LOL! Harry and Meghan have a gigantic mansion in California and were invited to stay in a billionaire's home for as long as they wanted. Why would they give a shit about some crappy little cottage in the country they fled? If they wanted a base in the UK they could easily just buy one. They probably only stay at Frogmore to be polite.
They have the power to totally shut Harry out of all RF events.
And? He barely attends the ones he's invited to now.
They have the power to help him financially, politically and emotionally.
What "emotional help" do they give, exactly?
They have the power to freeze him out of relationships where people have to choose between Charles & William he r Harry eg all heads of state, obamas etc etc
Please let me die and be reincarnated as the fly in the room the day Willy tries to get Obama on the phone to say "I demand you stop being friends with my brother or I won't be friends with you anymore and I'll also take my ball home and not let you play with it anymore nyah nyah."
Plus in terms of Harry's book, if King Charles or the new Prince of Wales object to any subject matter, they will have sway when it comes to objecting to certain parts being included and published.
LOL! That's the most hilarious part of all that you actually believe that. American publishers don't care about oversensitive foreign royals. You really think Charles and William will be shown the book ahead of time? They won't. If Harry is feeling generous he might send them advance copies, otherwise they'll have to wait and read it at the same time as anyone else. If there's anything libellous they can object after it's been published and go through the same court system as everyone else, but it will have been thoroughly checked by lawyers. It's not actually the 1700s, even though some MNers believe it is. America is no longer ruled by the crown, and Americans take dim view of foreign censorship.
