It is fair to say that J.K. Rowling, who once deemed Trump ‘worse than Voldemort’, is not The Donald’s biggest fan.

But the Harry Potter author said that while she disagrees with ‘almost everything’ the presumptive GOP presidential nominee has to say, she will vigorously defend his right to say it.

The celebrated writer was speaking about freedom of speech during her appearance at the 2016 PEN Literary Awards Gala in New York City on Monday night.

During her speech, she referred to a recent petition in her home country to ban Trump from entering the UK after he proposed a ban Muslims entering the United States.

‘Now I find almost everything that Mr Trump says objectionable,’ Rowling told the audience, at the American Museum of Natural History.

‘I consider him offensive and bigoted. But he has my full support to come to my country and be offensive and bigoted there.’

The best-selling author said that Trump’s freedom to make ‘bigoted’ remarks, ‘protects my freedom to call him a bigot. His freedom guarantees mine.’

She warned that attempts to repeal any of those freedoms, however well intentioned, means ‘we have set foot upon a road with only one destination.’

Rowling explained that if she was to back a travel ban of Trump, because of his offensive comments, then she would have ‘no moral grounds on which to argue that those offended by feminism or the right for transgender rights or universal suffrage should not oppress campaigners for those causes.’

‘If you seek the removal of freedoms from an opponent simply on the grounds that they have offended you, you have crossed a line to stand along tyrants who imprison, torture and kill on exactly the same justification,’ she added.

This is not the first time that Rowling has lashed out at the Republican candidate.

In December, she described Trump as being worse than Lord Voldemort – the evil arch nemesis of Harry Potter in her fantasy franchise.

Rowling was responding to tweets which compared the billionaire to Voldemort after he proposed a ban on Muslims coming to America.

‘How horrible,’ she wrote on Twitter. ‘Voldemort was nowhere near as bad.’
