I did feel a bit uncomfortable reading the OP of this thread. I don't think anyone should be fired for believing in gender ideology. I thought unless she's said something really heinous then Waterstones and this author are no better than TRAs cancelling GC women.
So I searched out what she said and I'm still on the fence as to whether I think this is a sackable offence rather than something that merits a stern warning. Obviously though I don't know Waterstones' social media policy or if there is more to her firing than just this one tweet.
I assume a GC bookseller threatening to destroy books by Shon Faye or Juno Dawson would be treated the same.
I also don't think it's fair of her to blame Christina Dalcher for her sacking. The screenshot I posted yesterday shows someone else tagging Waterstones. She seems to imply that CD contacted Waterstones demanding she be sacked, but we really don't know what happened.
I think she looks a bit silly talking about Waterstones being worried about upsetting CD and her measly 10k followers when the issue is that she, Tilly, tweeted out something that made her look bad, using her own name and photo and stated in her profile where she worked. It wasn't just CD and her fans that would potentially be upset, or put off shopping in Waterstones but anyone who doesn't want to feel judged by staff when buying books.
I do feel some sympathy for her. I'm guessing she got caught in an online bubble where you can get away with anything if you shout "trans rights!" This was probably a moment of foolishness where she didn't think about any possible repercussions, and now she's digging her heels in because it's better to say she lost her job for defending trans people than for a moment of stupidity.
