I did not say you quoted mined.
You said it was a mined quote. It is difficult to understand this charge since the question that prompted the paragraph and the answer were quoted in full, from a fully transcribed interview.
Ms. Khiliani did not speak about a general theory of grief - her comments are in a specific context.
Her comments were in the context of what she sees as the etiology of the mental problems of white people. She says white people's mental problems are the result of neuroses arising from repeating and believing "colonial lies". The mental problems of non-white people are from racism against them as well as individual neuroses.
Now, even though I think Khilanani is the kind of woman who has (or had) kept company with the neurotic white guilt liberals she is complaining about, and therefore some of her white clients may indeed have problems arising from their white guilt in the manner she claims, her sweeping generalisation of the etiology of white people's problems is unscientific, as well as hateful gaslighting.
But even though I think she is wrong about the etiology of white people's mental problems, that would make her therapy merely ineffective. But she's worse than wrong. She is genuinely hateful towards white people and I don't think somebody who hates white people can effectively minister to their mental health.
