In 2017 Hart shared an antisemitic conspiracy theory video about Jewish billionaire, George Soros. She liked a comment which said "Ein Reich'' (meaning "One Empire"),
She has also said that people with learning disabilities should be paid less than the minimum wage because “they don’t understand money”.
She also signed a letter accusing the National Trust of being “coloured by cultural Marxist dogma, colloquially known as the woke agenda”. Cultural Marxism is a far-right and antisemitic term.
