When I encountered things like her comment about folk music, I just put at down as one of her areas of ignorance. The problem was that, over time, reading a lot of her non-fiction, I kept running into more examples of how many areas of ignorance she actually had. And then she would make all kinds of self-assured pronouncements in those areas, frequently blowing off things she didn't know anything about.

Then I read some comments by people in her "inner circle" who agreed with her that one should examine things and use one's own judgment, not just accept something because someone says so.   But they tended to chafe a bit because, if someone questioned something she said, she could get real nasty.

Fascinating person indeed!
