When J.K. Rowling posted a series oftweets onTwitter about thetransgender community starting in 2020, she received significant criticism, including from mostHarry Potter cast members.[112] In response, Lynch tweeted "it's irresponsible to discuss such a delicate topic" on social media, and "I wish [Rowling] wouldn't.

After posting these tweets and receiving blowback for supporting Rowling, Lynch deleted her Twitter account in 2020. In an interview withThe Telegraph in 2023, Lynch stated compassion for both sides of the argument, "I know what it was like to be a teenager who hated my body so much I wanted to crawl out of my skin, so I have great compassion for trans people and I don’t want to add to their pain. I do also think it’s important that J.K. Rowling has been amplifying the voices ofde-transitioners." Lynch stated the backlash against Rowling has surprised her, "I just felt that [Rowling's] character has always been to advocate for the most vulnerable members of society. The problem is that there's a disagreement over who's the most vulnerable. I do wish people would just give her more grace and listen to her."[16]
