Evanna Lynch: "I think it's irresponsible to discuss such a delicate topic over Twitter through fragmented thoughts and I wish Jo wouldn't. That said, as a friend and admirer of Jo I can't forget what a generous and loving person she is."
Tom Felton: "I'm not really that attuned [to the trans debate]. The only thing I always remind myself is that I've been lucky enough to travel the world. Here I am in New York. And I have not seen anything bring the world together more than Potter, and she's responsible for that. So I'm incredibly grateful."
Ralph Fiennes: "I can't understand the vitriol directed at her. I can understand the heat of an argument, but I find this age of accusation and the need to condemn irrational. I find the level of hatred that people express about views that differ from theirs, and the violence of language towards others, disturbing."
Helena Bonham Carter: "She's allowed her opinion, particularly if she's suffered abuse. Everybody carries their own history of trauma and forms their opinions from that trauma and you have to respect where people come from and their pain. You don't all have to agree on everything - that would be insane and boring. She's not meaning it aggressively, she's just saying something out of her own experience."
Or even Nick Frost: "She's allowed her opinion and I'm allowed mine, they just don't align in any way, shape or form."
Or how about Miriam Margolyes: "I think everybody can be criticised, I think that's fair enough, but everybody's so horrid and nasty and unkind and I don't like that. I don't want to be unkind about trans...I mean, I'm a gay woman myself and you just have to put up with it. I don't know if [Rowling] has been badly treated but I think it was wrong that she wasn't invited to the celebrations for Harry Potter. You know, she created the whole thing. She may be wrong about some things. And women's bodies are tremendously important - I love my body, even though it's fat and misshapen, and I wouldn't be a man for anything. But trans - who cares? Let's be kind, let's be inclusive. I think there's an awful lot of nonsense talked about it. [...] I salute her as a very great writer and I think I like the detective stories best."
It should be noted that Miriam Margolyes (despite having a role in the films) apparently doesn't know JKR and has never met her. But she was still able to say something positive about her, something more nuanced than Watson, Radcliffe, Grint et al, who owe their entire careers to JKR.
These are examples of how you can disagree with someone, or decline to get involved, without putting the boot into someone.
So many other Harry Potter cast members have managed not to be awful about JK Rowling. But Emma Watson has been awful.
And let's not forget that she directly responded to JK Rowling's blog post by tweeting to the world that she donates to Mermaids and urging her followers to do the same. Who knows how many binders were secretly supplied to teenage girls without their parents' knowledge, or how many children were fast tracked onto puberty blockers thanks to the spike in donations that Emma's tweet may have generated?
OK she may not have referred directly to JKR in that tweet, but the timing was not coincidental. It was in direct response to JKR's statements. And in the intervening five years she has made many sly little digs.
So what's caused this change? She's finally seen the way the wind is blowing and realised that most people in the real world agree with JKR? She can see the iceberg looming and is scrambling for the life boats? Yeah, very classy. Unfortunately for her, the internet never forgets.
