On this matter I’m far from an expert.
You may be right and this is a serious matter.
I don’t follow the royal-news or have a TV, so I don’t think I’ve even seen the scandals about Harry. This may leave me less info about the day-to-day scandals but perhaps, just perhaps give me a distance perspective.
He’s the grandson and it is embarrassing - not as embarrassing as prince andy.
However in perspective of previous scandals in the Royal Family, this is nothing. Fergie, Diana with a Muslim, Chuckie with his horsie etc. etc.
And go back beyond the Queen (who has been a paragon of virtue) and her father and what we see Harry etc. doing seems almost normal - his Great-Grand-uncle Edward 8 was king when he did the same thing, plus he was a Nazi sympathizer to boot!
All of these have damaged the monarchy and all have come from within not without. And now that the tabs are unconstrained, nothing is hidden from the public. I’m not suggesting the monarchy will end tomorrow or at the guillotine. Simply that it’s in a kind of fin de siecle.
