I don't know Udayana. I've not heard anyone say anything about her ethnicity but then I wouldn't. She hasn't personally said anything and certainly Harry's father and grandparents were very welcoming to her. However I did read some of the racial abuse she received on Twitter - I don't do twitter but it was reported somewhere - and it was vile. We have some very devious right wing racist organisations here in the UK which have become more prominent in recent times, so that doesn't surprise me one bit.
However I believe the media build people up and then tear them down by whatever means they can, we've seen it before but this is definitely the worst I've seen. What gets me is that people believe the media.
