The chair of SoA is Joanne Harris, a TRA. Over the years she has tweeted some nasty things to and about other authors. After the attack on Salman Rushdie, JKR tweeted and received death threats. JH's response was a sarcastic tweet.
There's now been a petition organised to ask the SoA to consider whether their chair can be considered to be defending authors' rights in the light of her activism.
I'm an author, and as much as I find JH's activism unpleasant, I'm not convinced that a petition isn't just more cancel culture. I want to see evidence that what she's doing on twitter is affecting the work of the SoA - I think she is damaging the perception of the organisation, for sure. But she is an unlikeable person and it's hard for me to separate these things out. I don't want to sign the petition just because I dislike her. Any other authors who've signed it or are considering doing so?
