The royal family has for many years just been a curiosity and a source of amusement
True. And M&H now are too. Any opinion anyone has of M&H now is of their own making. I never read the tabloids, so knew nothing about them when they were in the RF. Now I can't escape them, so like many people, I have an opinion about them. It doesn't consume my every waking hour though.
Kate is a bit dull, but that's a good thing in a working royal, as H&M, Fergie and Andrew have evidenced!
On irrelevance of the royals - sure, they aren't paramedics, but the Duke of Edinburgh and Princes Trust schemes are just the high profile charities. I was impressed by Camilla's work promoting the domestic violence charity SafeLives during the pandemic, for example.
I am not a royalist but I try to give them credit where credit is due rather than dismissing the entire family outright. H&M will potentially do some good things if they stop airing their grievances (in my opinion).
As an aside, while I have never been Sarah F's biggest fan I thought her Youtube channel during the pandemic was well intentioned and highly amusing
