An upvote for you (if I could). I'm American but have lived in the UK for near 20 years. My great-whatever grandfather signed the Declaration of Independence so I'm hardly a royalist... So WTF am I doing living in the UK??? (the NHS etc...)
My general sense is that of respect for the Queen as a symbol. She did it right and wasn't a useless numpty like ... oh... all of the rest of them. Primarily nothing but B list celebrities. William and Kate seem fine enough, Harry and Meghan are .. irrelevant except to the nonces who have no actual lives, and let's not discuss Andrew...
Hopefully Charles will use the "soft power" he supposedly has to corral the professional sociopaths destroying this country (e.g. wind and solar power, given his supposed environmental leanings) but I don't know.... it very well may be all downhill from now. England (and by extension all of the UK) is destined to become a failed state.
Which is why I am looking hard at moving to Scotland (soon to be independent!) or even the EU to get the F out of here ASAP. It really is a transitional point.
