Thank you OP for raising this. It did give me a shock to see this decision, and made me worry immediately about the repercussive effect on public perceptions of decisions like Forstater, Phoenix, Meade etc. Already, when reporting on the issue, the Guardian managed (by quoting an 'expert') to misrepresent the cases as being about "people (who) ... find their colleagues’ views (are) completely obnoxious – but nevertheless protected because freedom of speech is something that … has been really promoted". When the ET had just very specifically found Jo Phoenix 's views to be not obnoxious (or at least, transphobic, which was what she was accused of). I think that actual transphobia (whipping up hatred, endorsing anti-trans discrimination or punishment) would not have passed the Grainger test.
The problem I have is that I do find Miller's views obnoxious, and antisemitic to boot. So I hope Bristol will appeal. Am I being inconsistent and irrational, because I am both GC and pro-Zionism? I hope not, but I'm afraid I'll have to say a little about his views to explain why.
I think the ET have fallen into a category error, or, just possibly, given Miller too much of the benefit of the doubt. Like GC views, Zionism (whatever you think it is) is a debatable political philosophy which has its pros and cons. I happen to think the pros outweigh the cons. Miller thinks otherwise, but he goes further, representing it as something that is inherently genocidal and an enemy to world peace, accusing the movement of using Jews outside Israel as pawns, and stressing the involvement of Jewish charities in pro-Zionist lobbying. Given the last two thousand years, you would have to have a tin ear not to hear 'Jews are bloodthirsty, Jews care nothing for gentiles, British Jews are traitors, Jewish money rules the world via an international conspiracy'.
Miller could have argued against Zionism, based on exactly the same facts, but without using the antisemitic tropes, and I would have listened (and argued back, obvs)
TLDR: Jo Phoenix wasn't trying to take away trans people's rights because she thinks they are stinky.
