In a follow-up tweet, the author wrote, "If sex isn't real, there's no same-sex attraction. If sex isn't real, the lived reality of women globally is erased. I know and love trans people, but erasing the concept of sex removes the ability of many to meaningfully discuss their lives. It isn't hate to speak the truth."

"The idea that women like me, who've been empathetic to trans people for decades, feeling kinship because they're vulnerable in the same way as women - ie, to male violence - 'hate' trans people because they think sex is real and has lived consequences - is a nonsense," she continued in another series of tweets. "I respect every trans person's right to live any way that feels authentic and comfortable to them. I'd march with you if you were discriminated against on the basis of being trans. At the same time, my life has been shaped by being female. I do not believe it's hateful to say so."

In Radcliffe's blog post, the former Harry Potter alum added that he was still "learning how to be a better ally," before sharing resources for people who want to learn more about transgender and nonbinary identities.

The 30-year-old actor then went on to address fans of the fantasy novels who expressed their disappointment on social media following Rowling's comments.

"To all the people who now feel that their experience of the books has been tarnished or diminished, I am deeply sorry for the pain these comments have caused you," he wrote. "I really hope that you don't entirely lose what was valuable in these stories to you."
