@FellOutTheLoft I'm sure you will have noticed that the gofundme has increased quite a bit since being discussed on mumsnet. I'm not on X - and would suggest you be very cautious about what you say there - but I've donated. I hope the number of donations is some comfort, you do have support.
It's difficult to comment really on these cases because we dont get to see all the evidence. At an employment tribunal I suspect your best bet may be to go with sex discrimination and showing that Kevin Thompson's statement that if he had made similar comments about women he "would be swiftly dealt with about misogyny" was not actually true because male officers in Northumbria police have not been dismissed for worse breachers. A few public cases elsewhere does not mean that males in Northumbria Police would have been dealt with in such a severe fashion. Also the environment in which you worked - that you were working on cases that show men at their worst.
You were previously required to take performance required improvement - why? If this was because of GC views then it needs to be part of the argument that you were, in fact, being targeted for being GC and were treated unfairly. That Northumbria Police had to be taken to court to stop them unlawfully appearing at Pride needs to be brought up as part of the evidence of a hostile environment.
"Cocks in frocks" was crude but men in dresses IS a gender critical view. You expressed your view badly but still a protected view badly expressed. Again context is important, this was a comment made when you were distressed by a policy subsequently amended as it was illegal and it was claimed objectors would not be penalised for refusing to search. That commitment seems not worth the paper it was on.
Tina Brown when initially asked about the "all men are rapists" comment said she hadnt heard it. She gave a semi plausible explanation of why she "remembered" it after being specifically asked about it by CH but it's a weak point. BC said they felt pressurised into saying something untrue, a useful comment. Anyone else who would be a useful witness?
Damon Hall was offended by the curfew comment but said you laughed after it. He admitted to thinking it was "dark humour".
Put the gofundmetarget up if you can.
