I would say that the image most people have of the Queen Mother was a carefully calculated persona. When I had lunch in the royal suite at the Grand national, I could see a wide range of personalities in her. When she lost her pencil she became extremely autocratic and was ordering the ex foreign minister around like a foot servant. I can well imagine that she had a hate list. I also think she was much more intelligent than people think she was. All royalty are humans but well indulged ones. They have prejudices and subjective views on things and people. They are also smart enough, with the possible exception of Prince Philip, to hide their views. Of course, having servants everywhere does not help keep those things secret.
