She told a jury at Isleworth Crown Court that trouble began at the Tesco store in Kensington, West London, when she offered to help the woman, Mounia Hamoumi, and her husband unload their shopping trolley.
The court was told she had overheard the husband refusing to help his wife because he was too busy looking after their children. "I told him that is what feminism is all about, women helping women – and he told me to 'get lost'," claimed Heathcote-Drury.
But prosecutor Nermine Abdel Sayed said: "You took objection to that inequality didn't you? Coupled with the woman wearing Islamic dress, you waded in and instigated the whole incident. "When your offer of help was rejected you became more confrontational and you very quickly lost control and were shouting at them.
"Your tone was aggressive and you used the words 'suicide bomber' and 'terrorist', and told them: 'I am a British citizen. I don't know where you are from.' You went to the woman and pushed her." Mother-of-three Mrs Hamoumi was six months' pregnant at the time of the incident which happened on November 30 last year.
