I used to think this would burn itself out like any other fad – but now I'm not so sure, having seen how the SC decision has been received not as the final result, but as a new stage in an endless argument, as creating confusion, as "let's wait for guidance", etc.
Now what I see instead is more systemic – a crisis brought about by a culture of weak leadership, where the state has (deliberately) stepped away from acting like a central authority, relinquishing that role to Stonewall and all sorts of other bodies. The result of that is endless politics at a much lower level than it should be. It makes the public the target for campaigning downwards, because that's the level where these things are controlled now.
But the public is terrible at this! It can't set a frame for debate, it can't take a decision, it can't enforce a compromise.
It means that mechanisms for social change have become completely chaotic and needn't reflect where society is actually at at all. Instead you just get struggle in whatever fora are available, in whichever manner activists choose, and there's no way of achieving a settlement.
Unless that broader political culture changes, there's no particular reason why it shouldn't go on like this. That might mean arguments about trans going on for many more years, or tomorrow it might be something else entirely – there's no way to tell, it's just a function of how activism works a weak system. Oh joy.
