I completely disagree.
When Meghan and Harry got together the reaction from the vast majority of people was a positive one.
When they married thousands and thousands of of people lined the streets in support.
It was widely felt that she was a fantastic thing to happen to the Royal family.
No, all the criticism of Meghan has happened since she and Harry started lecturing people on how they should live whilst behaving in a hypocritical way themselves.
Harry is getting just as much criticism over this too, although people do seem to believe that Meghan is behind most of it and that Harry is totally beguilled by his wife.
I tend to think there's some validity in this, although Harry is understandably a very troubled guy, particularly with the press and their role in her death.
Whilst there are always racists who will jump on these things, I don't believe her colour or ethnicity have anything to do with all the criticism.
If they want to leave royal duties that's entirely up to them. However, they can't continue to receive tax payer and Royal money if they do imo.
