So many thoughts about this.
It feels as though DT has got carried away by the wave of applause following him around. I've seen three clips of him over the past six months or so, at ComicCon - or similar events. He's been asked directly by young fans who ID as Trans if he supports them, and he's always stated that we are in the wrong and twice he's on camera telling them that we can F**k Off. This is before the last week's absolute shower.
His wife has been banging this drum much longer than him and has been, imo, really irresponsible. Before leaving Twitter/X she spent a while posting loads of 'anonymous' messages sent to her by teachers, who were all vowing to ignore the Govt draft guidance on not teaching GI as fact in RSE lessons. I thought that was a really dangerous thing to do - encouraging teachers to risk breaking the law if the consultation results don't go in their favour.
One thing I've noticed is that since Staged and Good Omens, both he and Michael Sheen have got these new young fanbases. They seem to be very young, a lot of them are neurodiverse and loads of them seem to ID as Trans or non-binary.
There is a huge crossover between Dr Who/GO/Staged/Neil Gaiman fandom and it all seems to focus on DT/MS and their partners. I imagine at a time in their careers when they thought they would be slowing down or adjusting to playing older parts, they suddenly have this incredibly enthusiastic young fanbase, hero worshipping them, asking to be adopted by them and their partners, and producing huge amounts of fan art and gay fan fiction about them and shipping them as a gay couple.
I think it's turned his head and probably shored up his belief that he has things of great weight and import to pronounce. His wife is hugely invested in social media and in her identity as an 'ally' and so he's gone the same way, without any thought of consequences whatsoever.
In the same way that he obviously feels the need to publicly champion his son, he also probably doesn't want to upset or rock the boat with his new fanbase. If he did, he knows they'd turn rabid.
None of which excuses his rank misogyny. Or his clear assertion that 'it's all down to Georgia' - that's a statement that can go either way, so felt like a bit of surreptitious distancing disguised as 'thanks darling', in case it all goes wrong.
