I don't know the answer to that one. I just ask the question. Before Jade went ballistic, Shilpa was asked whether she'd marry a white man. She replied she would only marry an Asian.
I don't know whether this is racist or merely cultural or an expression of personal preference. Is this a "do you prefer oysters to snails" question?
Years ago I interviewed Jane Asher in her Chelsea cake shop. I asked her whether she'd mind if her kids married black people. She replied she would mind. She couldn't articulate precisely the problem but there was no doubting her unease at such a prospect. At the time I privately concluded her reply was racist. The media didn't follow up.
Am I wrong? I honestly don't know.
