The twin studies you are citing precisely require the distinction you seem to think should never be made (because "Nazi shit"): what is caused by underlying genetics vs what in the environment effects gene expression. That is why they are interesting

Chu doesn’t see the difference between twin studies to determine the genetic and environmental influences on traits, and Nazis stitching twins together for shits and giggles. For him even your genes are just an ‘environment’.

I'm on record as saying I think if I had different genes I'd still exist and be me, at least to the same degree that I'd still exist and be me under the counterfactual where I was born in a different city or a different year

Was it sensible to go ‘on the record’ with that? In what sense would something with different genes and different environmental experiences be you? If this was possible why is there only one of you?

Hahahaha he keeps getting better and better. Now a genetically different 'Arthur', subject to (necessarily) different environmental interplay with genes, is still the same person? Wow!

And he was criticising those who accept biology of claiming there is an ‘ideal you’ - but here he’s arguing for an ‘ideal you’ that exists outside of your biological form.

Not really I don't think these counterfactuals exist or that you can say there's an identity that persists through them except as a spectrum of similarity So perhaps my point was poorly phrased

So how about this The version of me who got two more hours of sleep last night is JUST AS fake and nonexistent and JUST AS MUCH "not me" as the imaginary version of me that has XX chromosomes

So your earthshattering point now is: other possible versions of you do not, in fact, exist? Thanks, I guess...

And yet transgender people claim their ‘gender identity’ is innate. So is it an intrinsic property or something they acquired?

For what it's worth, I think the essentialism of the "born this way" narrative is harmful and I've seen moving testimony from people whom it's harmed Gender identity can change, at least for some people in whom it demonstrably has, and that's no big deal
