I do think there's a mix : a reject from a part of the establishment seing a divorced actress joining the BRF, a reject from a part of the pro Brexit Britain seing a foreigner joining the BRF and a yes a reject from some seeing a bi racial woman joining the BRF.
But maybe in order to counterbalance those challenges, the Sussexes seem to try a bit too hard, and too fast, to be relevant, instead of calmly, discreetly but firmly establishing themselves as pillars of the BRF, Cambridges and Cornwall style.
I don't think it's easy and there's no tutorial to be a perfect royal. The only thing i know, and i see, is that their PR has been just chaotic lately. Maybe a return to fundamentals, the good'ol, a tad boring but understated engagements across the UK could help to fix the somewhat blurred image of the last few weeks...
