The Witch Trials of J.K Rowling

"I have long supported J.K. Rowling because I don't think what she's saying is transphobic," says writer Megan Phelps Roper. "She has consistently said that trans people should be free and exist but they should not impinge on women's rights," adds the author of The Casual Vacancy, a new book about her time in Harry Potter. 'The Witch Trials of J.K.' will air at 9 p.m. ET/PT Thursday night (9 p.m., ET Friday morning) with an all-star cast including Tom Hiddleston, David Walliams & Emma Watson.
