Well it was Harry who said the racism doesn't exist (despite taking an award for standing up to it)
And as pointed out repeatedly, Meghan has never herself accused the RF of racism.
So taking them at their word - including the words in Endgame, which are "unconscious bias" - then no, there was no racism by the RF that "the brown woman" (as pp put it) has ever complained of.
It is far from clear what was said, and whether any concerns were fair ones. After all, as linked on the other thread, there were articles and tweets from the time of the engagement onwards about whether Catherine's slightly olive skin tone would mean the next heir was unusually dark skinned. So there are all sorts of possible scenarios about comments, including ones that could be positively helpful.
Recollections may vary is a brilliant phrase. And for the general public, it means "you don't know what's been going on"
And I think that, unless Harry is prepared to say what was actually said to or in front of him, plus how he told Meghan about it, then we cannot draw any conclusions about it, and it is very unfair to assume that something as serious as racism had occurred, or indeed something as pernicious as denial of racism.
H&M do not have a good tract record of their truth actually aligning with verifiable events.
Another pp pointed out that class discrimination was also an issue - I think that's relevant. Both Sophie and particularly Catherine were on the receiving end of that, also Fergie to some extent (protected by her friendship with Diana, but still blasted as "vulgar, vulgar, vulgar") It's clearly not an easy world to join.
