"Although I imagine our RF is probably much more stuffy than others."
I think there may be an element of truth to this - our monarch is well into her 90s after all and has been queen for a very very long time but....
... I'd also argue it's our media. In light of the clothes the queen wore when she was young, it seems pretty unlikely that she has any negative thoughts on Meghan wearing off the shoulder or dark nail polish, for example. Except, the tabloids were all about it breaking royal protocol.
Every thing Meghan and Harry do is framed as "upsetting" the queen. And while Kate gets less of this now on the negative side, she's had her share in the past. And of course, even when being "positive" it's so often framed as if the only thing she's considered is the queen.
I was rolling my eyes last week at how "upset" the queen et al supposedly would be that Archie didn't come. hahaha - clearly the writers of such things have no very elderly relatives. Mine love my DC, are brilliant with gifts, care massively about how they're doing etc. But actual interaction is limited to politely looking at the odd photo or, in person, leaning down to say hello before heading off to do something non-child related!!!
