There seem to be two issues. 1) they were racists and mean to Meghan. 2) the royals are useless.
The first seems patently absurd. Sure they were mean to Meghan, but she seemed to think the gig she married into was a reality or game show. The second is imo more complex. The idle rich are useless ... and worse. Capitalism requires the rich, but if they haven't earned being rich, they're parasites. But the brits are a more racially diverse society than we are, and the royals do play a part in unifying their society. Harry needed a wife who was happy being the support system of a serving military officer. He picked the wrong girl. Race is irrelevant.
But if I were a brit, I'd probably at best be pretty ambivalent to them sucking off the tit
I don't know what makes you think that "the gig she married into was a reality or game show." I don't know what Harry needed. These two humans seem to be very happy together, loving and mutually supportive; they have each other's backs. Seems they may be best friends between the sheets.
After all of the negative shit that heterosexuals have put heterosexuality through, all the power-tripping, ego crap, trying to dominate, all of the "I'm better than you" stuff, it's refreshing to see heterosexuality portrayed in a positive light. The aspects of the inauguration that particularly pleased me were Doug Emhoff standing next to his wife while she took the oath of office as Vice President of the U.S. and then looking for her lost earring, and Dr. Jill Biden pausing with her husband, the new POTUS, in front of the White House front door to hug each other before entering for the first time in their new roles. Honor your partner. It's funny that the song that just came up on my Ipod as I type this is "Love Lift Us Where We Belong." Heterosexuality can be positive without denigrating LGBTQs or anyone else.
