Lesbian is a non-man who is attracted to a non-man, university says sparking outrage from JK Rowling

JK Rowling has blasted a university in America for saying a lesbian is 'a non-man attracted to non-men'. 

The Harry Potter writer, 57, slated the US medical school for the new definition in its LGBTQ guide. 

The guide states that 'lesbian' should not just include women but also non-binary people, according to a report by The Sun. 

It therefore refers to lesbians as 'a non-man attracted to non-men'. 

Ms Rowling took to Twitter to criticise John Hopkins University in Baltimore, Maryland, writing: 'Man: no definition needed. Non-man (formerly known as woman): a being definable only by reference to the male.'

She added: 'An absence, a vacuum where there's no man-ness.' 

The author's tweet comes after the charity Oxfam were told to apologise and delete a section of their Pride Month advert after it brought out a video apparently portraying Ms Rowling as a villain with red eyes. 

The Government watchdog is said to be assessing concerns surrounding the charity and is considering its next move after the row which has engulfed it since the video shared on its social media accounts.

The video featured three figures with evil-looking eyes - two men, and a woman wearing a 'TERF' ([trans-exclusionary radical feminists) badge who appeared to look like the Harry Potter author.

The charity insisted any likeness is coincidental and it quickly removed the footage from its social media - but campaigners say people with gender-critical views like Ms Rowling's could be marginalised at the organisation.

It came as one former employee claimed they were forced out of Oxfam over her support for the author and arguing its bookshops should continue to stock her published works.
