Todd Spangler NY Digital Editor J.K. Rowling said she knew her comments about trans women nearly three years ago would land like a “hand grenade” on Twitter but claimed that despite the backlash, “a ton of Potter fans were grateful that I’d said what I said.” “I absolutely knew that if I spoke out many people who would love my books would be deeply unhappy with me,” the best-selling author said in the latest episode of podcast “The Witch Trials of J.K. Rowling,” released Tuesday. “Personally, it has not been fun and I have been scared at times for my own safety and, overwhelmingly, for my family’s safety. Time will tell whether I’ve got this wrong. I can only say that I’ve thought about it deeply and hard and long and I’ve listened, I promise, to the other side.”
