Stephen Fry is a bit stuck, I think. He's built his career on his intelligence. He's Mr QI. And yet he fell for an ideology someone with no education at all could see through. As KJK said, "I'm not a vet but I know what a dog is". Everyday people without his education could see the emperor had no clothes.
I do believe Fry has caught up to that at last. Hence the Triggernometry appearance and all the faffing about, implying being kind is more important than being right. He knows he'll look a fool if he continues to blindly parrot the TWAW party line. But his ego won't allow him to take the final step of humbling himself. He can't say, "I'm sorry, I was wrong and I was stupid". That'd be unthinkable to him. Complete ego death. Unfortunately for him, most of us (women in particular) are so sick of his shit, that humility is his only real shot at forgiveness.
If memory serves, Fry also personally funded a young women's double mastectomy. He has to believe trans and trans surgeries are in some way justified, because it brings up really uncomfortable moral questions if he doesn't.
