Liz’ horrid behavior over Diana’s death used up every ounce of criticism there was.
Horrid by American tabloid standards, maybe. She has behaved steadfastly for more than 60 years as the caretaker over a monarchy going back 1,000 years, where the price of privilege is personal sacrifice, not emotional indulgence. She wanted it to remain a private family matter, was primarily concerned for the impact of the death on her very young grandsons, and did not want to turn it into a celebrity-ridden spectacle; but that it became.
Harry himself has said that because it became a state funeral, he had to walk behind his mother's funeral cortege at age 11 with the eyes of the world upon him, that it was excruciatingly painful, and that in hindsight, no child should have to do such a thing. But the ghoulish public clamored for a spectacle, and so did the tabloids and Tony Blair.
As you may be aware, Harry went on to choices of not going to university in spite of being 3rd in line to the throne at the time, plus alcohol partying, probably drugs, random fornicating, a couple of disruptive girlfriend breakups, and at least two widely publicized scandals that embarrassed even his fans as well as the throne.
He has recently matured outwardly through his admirable military service and veteran's charities, but admitted only last year to having emotional health issues around his mother's death he had not previously been able to deal with. He's not out of the woods yet, and judging by this carnival wedding, he may not be for years to come.
And you fault the queen?
