I hope I'm not being overly optimistic but I think the tone is shifting. I had a read around online last night and this morning and 90% of what I'm seeing, from journalists, celebs and normal people is support for JK and condemnation of Daniel Radcliffe et al. Even LOJ was being put on his place last night (see Robert Webb's tweet and the thread that followed).
There are still vocal people on Twitter but who are they to dominate the debate? What are their qualifications, where's the social proof of their authority?
It reminds me, in a way, of the hysterical Corbynites the morning after the Tory landslide in December, still screeching that Corbyn was loved by most of the country, and that he was more popular etc. Demonstrably not - but their fury and conviction overruled their sensibilities. I reckon it's the same group, more or less. The bullying and hectoring far left.
