Hit post too soon.
I meant to say, as far as I can tell, what people think Kate has done wrong is to marry a prince, rather than doing something else. Presumably that means that anyone who married William would automatically be in the wrong.
So should William simply live alone all his life because anyone who marries him is wrong to do so?
Or is it that people think that Kate simply isn't "worthy" enough to have married a prince? Does she just not deserve the life of privilege (and severe restriction, but that's a whole other discussion) that has come her way? Should wealthy, privileged men only marry high-achieving, brilliant women?
People always say "oh but the royals are just like this - why should they get all the money and kowtowing?" If they are just like us, then they should be free to fall in love and marry whoever they choose, without their spouses being criticised simply for becoming their spouses.
William chose to marry someone who appears to be a quite nice, quite clever, quite attractive woman. She isn't a novel-prize winner. She isn't a brilliant scientist or politician. She isn't a great orator. She's just a fairly ordinary woman who is now in a fairly extraordinary role.
Yes, she could have done something else. But perhaps she actually wanted to marry the man she fell in love with and be happy, or as happy as she can be. How very dare she!
