I think it's ok to have different feelings about going public with everything. Harry and Meghan are "of their time" in the way they choose to communicate, and the subjects they choose to communicate on.
I personally dislike the trend, and do prefer more restraint ("pudeur" in French - there's no real English equivalent). I remember when I did my MA in documentary photography, my tutor put a tremendous amount of pressure on me to document the community I grew up in. I had an incredibly strong sense this would be a deeply wrong thing to do towards my family and the friends I still had there, and I'm so glad I didn't cave in. I still really struggle with the photography world's tendency to do "my mental health problems" projects, or "my mother dying from dementia" projects). I find the capacity of art to transcend problems by capturing universal dilemas more elevating.
So between the Queen's communication style and Meghan and Harry's, I'm naturally drawn to the Queen's - not that I could ever achieve that level of self-control.
I think that people who like me, are allergic to this general positioning of self at the center of everything really deeply struggle with the communication style.
I do find there's a big danger in declaring that people are only allowed to feel one way about this - or else they deserve to be accused of being right-wing or torn apart for lack of compassion.
Problems can be nuanced, and I have no doubt that racism is a problem both in the British press and most likely with some members of the British Royal Family. I think that truth can coexist with a concerns about Meghan and Harry's motivations or behaviour in other aspects.
One problem, when you're concerned about people being deeply manipulative, is that aside from removing yourself from their sphere of influence as best you can, you feel quite powerless against them. Some topics - including, sadly, mental health these days - are particularly exploited by deeply manipulative people because they provide such a shield against acceptable criticism.
Nothing can be done to prove a hunch, in this regards. I do believe that some people who are expressing strong feelings about this interview are not racist, sexist, or right-wing - they just have very strong
alarm bells ringing and can't overcome them.
I think sadly, the best course of action when you feel those alarm bells it to shut up and hope time will do its work in bringing the truth to light. There are serious topics at stake here - racism, and mental health. It's probably worth "being wrong" to let the right causes behind the possibly wrong voices be heard.
