It didn't occur to me that she was mixed race until someone else pointed it out, that was before the wedding. If there is a problem it is that she doesn't understand what it means to be part of the royal family and doesn't seem to want to learn. It seems that no-one can criticize her for fear of being called racist and that helps no-one. If there is a valid criticism to make then it must be made as the alternative will only lead to more issues.
FWIW I don't agree with the monarchy but accept that I am in a minority. However I think that while we pay for them and their expensive tastes then they have to understand that they keep to certain expectations. So , they are polite to us plebs, they allow us glimpses of their life and kids and they don't complain. I think Meghan needs to understand that she represents the royal family especially the Queen when out and about and not just certain sections of society.
Most people in the UK, I think, don't give much thought to a persons race; we think much more about how they behave. In fact the population of the UK in 2011 was 87% white, the next biggest ethnic group was Asian ( which means from the Indian sub continent ) and Black was behind that. Most came to the UK after the Second World War, although some came between the wars, including some of my family members. I mention that because the UK is not the USA , we don't have the same issues with race . Slavery was not in existence in the UK in the way it was in the USA. There was slavery in the Caribbean but those slaves were emancipated before the USA did so with their slaves. Many black people in the West Indies considered the UK to be their motherland . I agree that some individuals are racist but there was never legislation to uphold that view.
Finally I have mixed race family and friends . My thoughts about Meghan aren't to do with her race but are more to do with the lecturing we seem to be getting from Harry and Meghan at present.
I suspect that I will now get the sort of comments that tell me I am racist , which will amuse me because you don't know my race!
