Rollo May once said "If will remains protest, it remains forever dependent on what it is protesting against".
Harry reminds me of this. His marriage is founded upon its perfection as a path for his anger, which Meghan probably realised was the path to his heart, no doubt agreeing that he had been ill done by, and together they'd stick it to those that had marred poor Harry Windsor's life. And she could always point to abusive racism on her side to join him in it.
But in truth, neither has suffered much. Harry is a child of immense privilege who received honours and wealth that he never earned. He idealised a mother whom most of the rest of the world knows was no saint. Meghan is no ghetto child suffering want or poverty or obstruction: she grew up middle-class, her indulgent father who spoilt her rotten is a two-time Emmy winning lighting director, she went to nice schools, a very good university, joined a sorority, and set out to conquer show biz, in which, although she had only modest success, she still supported herself in well, enjoyed herself immensely, made friends (mostly white) who helped her, married a man who helped her get that one modestly successful acting job, and when she met Harry was living with another very attractive and successful man. Harry had all the pussy he could handle, a decent military career, and had he been inclined to work hard, could have easily gone to uni himself and gotten a degree in land management, eco-conservation, for which his family would have been cock-a-hoop with approval. He didn't. He left the military, fucked around aimlessly and the blamed his family for having no "role", lost the one woman he probably loved in a spirit besides anger and resentment, and finally ended up with a nearly middle-aged American divorcee who helped him to the satisfaction of fucking over the family that had been trying for years to do something to help him - except, of course, murder his brother and his brother's children so he could be First.
Neither of these two twats, in reality, have much to complain about except in their own minds - they resent not having things that they are either unsuited for or that were unrealistic (particularly in Harry's case). They have lived lives of comfort, had lots of fun, travelled, seen a good bit of the world, lived in homes ranging from nice to quite upscale by the rest of the world's standards, and had access to plenty of resources to shape their lives.
But for Harry, resentment is the motor that keep him going. For Meghan, resentment and protest gives her a hook on which she can now hang the ambitions that didn't quite fulfill their wished for scope in either show biz or royalty.
Unless Harry can move past the anger and resentment rooted in some adolescent warp (remember, this is the boy who at 14, when he well knew better, stripped naked and ran around at his father's 50th birthday party, embarrassing his father and brother and the guests), anger and resentment will remain his emotional anchor, and with it, Meghan Markle, who is nothing if not acute enough to realise it's what keeps them together.
It's really quite sad. And the thing is, people can sense it. No matter how much lipstick Meghan particularly tries to put on this pig, people can sense the bottomless pit of Never Enough and massive entitlement that animates the couple.
And that's why so many people dislike them.
