@FreddyKreugersWife I'm afraid you will argue till you are blue in the face. This is one point that the anti Meghan brigade hold on to with their might as they don't really have anything else worth much. It's just easier to accuse her on this and harder to defend.
As a previous poster said, the so called lies were dissected, by a publication ( I think Private Eye of all publications) and found not to be true. I can believe it. I did not read them, but someone once showed me one of those so called lies. It was a picture of MM with her sister Samantha and a claim that MM was with her during graduation in a certain year. She showed me that the 'evidence' of a close up of the graduation certificate that Samatha was holding was totally different to the one in the original picture. The logo was in the wrong place for a start - on the bottom on one picture and on top on another picture and was really not the same certificate (the point was to say MM had seen her on certain dates). I think people do not read, but while they are willing to question MM, they will readily believe the DM. It was the DM which came with the original list of lies and the Irish Times and others reported from what I gather.
Back to your point.
MM looks and "acts white' to a lot of people. Some people who may not view themselves as racist, will say she is just like say Blake Lively - except not really. So every time her 'black' side comes out, they get a shock and suspicion. Eg, they don't like her racism accusations etc. They also do not like her showing other cultural differences like the marriage. This just jars.
On my travels to the US and interactions with people of colour , I have found the USA in general does not celebrate Kwanda, but it does not stop black people from making a big deal out of it. I was also surprised to find a lot of black people with what sounded like muslim names when they are really not.
In the UK they like to compartmentalise , and MM does not fit the pre-determined boxes. So here people understand an African, Asian or Middle Eastern etc. having pre-set known rules and regulations. Anything else seems odd. Unfortunately, the media is also pressing for these stereotypes and pushing forward the idea that what she said was false, too many were happy to grab this straw.
Good on you for having an open mind though.
What is California culture? Last time I checked the state is mixed, with a huge south American culture, that may not all be recognised legally.
