"It would be hard to overestimate the effect of this sort of snobbish condescension on the formation of Margaret Thatcher's character. The discovery that all the trendy people were against her only confirmed her certainty that they were all wrong and reinforced her righteous sense of persecution. She encountered the same patronising attitude when she first became Leader of the Opposition in 1975. She had probably met it already at school, where she was used to being a loner who was not allowed to go to dances: it was precisely the attitude Alfred had tried to arm her against by urging her to follow her own – or his – convictions and ignore the crowd. But nowhere can it have been more brutal than at Oxford, where she went up naively expecting to find rational inquiry but met only with arrogant superiority. This was her first encounter with the liberal establishment and she did not like it. It hardened her heart: one day she would get even. Janet Vaughan...gets no warm words in her memoirs. The experience forged her lifelong view of herself as an outsider, part of a persecuted minority, which never left her."
