The only things of note that could come out of the Oprah interview that would rock things would be be if:
1. Harry states that his father is bisexual and that he regularly gives and receives fellatio from male equerries, and that he is too morally unworthy ever to become Charles III.
Ignoring youre obvious homphobia - to whit gay = unfit to lead
Gay kings are pretty much run of the mill
France used to prey for an English king to be gay or a womaniser - because that kept them busy - those that werent tended to occupy there time by invading / fighting the French
2. harry states that he loves his brother Wiliam, but that in his opinion he is too weak a personality and totally unsuitable to ever become King William IV.
Again unsuitable kings are not uncommon either - regardless of Harrys views (as portrayed by you) on the matter Wills is after Charlie
3. That his mother was assassinated, and that MI6 called in the Israelis to assist in the 'accident'.
That would rock nothing - those that believe it would cheer him on - everyone else would point to the blatant logic hole and exopress concern about what harry is sniffing
Well done or managing to inject your usual anti Israeli bollox into a totazlly unrelated matter
5. That Buckingham Palace as damage control are compelled to reveal to the nation that DNA tests confirm that Harry is not the biological spawn of Charles.
Firstly - the number 4 usually follows 3
Secondly Wibble - How would anything Harry says compell this, given he thinks he is
Never mind the fact cretinos conspiraloons aside its never really been in doubt - not least because Harry was born 2 years befor Di met Hewitt AKA his 'dad'.
