Violent shove or a spat btwn brothers? Sure. My sister and I are 18 months apart. I hit her with a hairbrush. I'd never physically hurt anyone but her (we're 40).
Waite Katie...a bunch of people picking on a 19-year-old girl. For real, are we expecting the college kid to stand up for herself like the professional actress. Sure. JFC is Kate a privilaged brat? Yes. Did she not do the boating thing b/c she wanted to do a vaca w/ her boyfriend? Yes. Has she been a mean girl? I'd bet on it.
Did I say the Daily Mail wasn't racist on the "outta Compton"? Nope. The Daily Mail is American racist (UK and USA...cousins).
Has Meghan had obstacles Kate hasn't? 100%. Diana hasn't? Absolutely.
I'm very white and blonde, and no one discussed what I'd look like when I was born other than dear God I hope she doesn't get her father's Polish/German nose. I've heard that millennial biracial couples discuss skin color; don't know. If Kate or William asked it's...dumb, PR wise. Like biracial families say, these conversations happen.
But proof is in the pudding, as you said. There's way more dollars being spent on PR in Calfornia (and honestly, I'd work for H&M tomorrow in PR and probably help them b/c I'd be honest) than Windsor.
Kate and William -- don't work enough for their lives (also, love her, Diana laughed at how much Anne did). All these people have faults; it's whether or not their fans can admit it.
