>The Crown essentially portrays a Christian monarch as a positive figure who sticks to tradition and does her duties, and this makes her great. She puts family first, duty over selfishness, etc.
>Why would they make this show?
Because we all know what comes next, where she loses the Empire and her subjects become culturall and ethnically suicidal. As a regal figure she is pretty much powerless curiosity, so as far as most poeple watching it are concerned this is just IRL "Frozen".
>Even in the 50s Anglicanism seemed to be doing okay. Now it's the church of trannies, guitars, gays, and women priests.
Don't be fooled. The rot in Anglicanism was always there and it started to get out of hand in the early 20th Century, with priests flying red flags over churches and encouraging workers' politics. Even the anticlerical Orwell remarked at how effective the Anglicans were in leftist circles, and noted how much nicer and comfier and liberal it was than the Catholic Church.
