She has dumped her sick elderly father,
Her father has used the media for his own attention. She obviously had and has a very fractured relationship with him and if she feels he hasn't been a good enough father to be a part of her life then I can't see why she should be judge for that.
sat sulkily at Wimbledon having had all the plebs from all around her removed
Media painted bull.
lacks the grace to invite any of her family to her wedding apart from her mother,
Again, if she has a fracture relationship with her family then she doesn't owe them anything. Anyone outside the public eye wouldn't be forced to 'make nice' with family just because of blood ties and 'its a wedding'.
put Oprah where her family should've been sitting (implies social climbing extraordinaire),
Making your own assumptions.
denied her own mixed race heritage for a long time,
Evidence of her denying her mixed heritage?
flew on private jets whilst asserting eco credentials,
Obviously people in their position should make a point of only flying Easy Jet. Or hitchhike.
spends unnecessarily extortionate amounts of tax payer money on clothes,
She can afford her own clothes, should she just wear supermarket clothes made in sweatshops? More to the point, Kate gets dressed by the taxpayers and did so for much longer than Meghan did - no outrage about that?
flew all the way to South Africa to highlight the conditions of the people there but only managed to moan about how no-one asks how she is in spite of having staff to help with the baby
Thats the only singular thing she did on the entire African trip what 'have a moan'?
Gets through said staff at a fairly brisk pace,
The horror. And again, no actual evidence of this bar the media reports.
allows taxpayer money to be spent refurbishing her home and paying for her wedding without any sense of duty or payback,
Again, as opposed to other royals doing exactly the same?
spent the Disney premier touting for work when he should have been at a long standing prior engagement in honour of army vets.
Harry told one person that his wife was good at voice work, so you translate that as not doing any of his army vet work?
The whole idea that they can set up a foundation to serve charities and cream off some money for themselves to live their very expensive lifestyles.
Sorry, not sure what you're suggesting here but it very much reads like you belive they are taking charity money to fund their lifestyle? I'd be very careful if that's the case.
