Hi again @Tandora with a bit of insomnia I've been reading through your posts with an attempt at a summary of your core argument below...I'd be really grateful if you could let me know if this is correct or any changes suggested. I've given it a name, I see it as different from i.e. The Trans Argument from Kindness.
Trans Argument from the Biological Complexity of Sexual Development
We are continually discovering more about the complex nature of human sexual development.
Sex is multidimensional. For instance, some women have a male chromosomal pattern (XY) but present as phenotypically female.
Biological sex involves an intricate, ongoing process of development across the body—including the brain. It encompasses many factors: genes, karyotypes, hormone signalling, and more. As well as major variations, there are subtle differences across individuals. Of particular relevance is how sex hormones are produced and received, which has profound organisational effects on the brain and broader neuro development.
Trans identity roughly defines as a firmly held sense or belief about one’s self that does not align with one’s genitalia or chromosomes etc. It challenges the idea that sex is a straightforward binary fixed at birth, an "external" that children come to "know" in their day to day interactions.
Much like other aspects of neurodevelopment, there's growing evidence that being trans has biological underpinnings linked to developmental sexual variation rather than something somehow separate to it.
Conclusion: Transness is not a consciously chosen "false" belief—it reflects a real and natural part of human diversity and development. Understanding this complexity can help shape how we support and accommodate transfolk, as we do with other forms of human variation.
Apologies to other posters but probably won't get a chance for other debates/replies. I'm not advocating this view, I have the biological knowledge of a cucumber, just looking to understand better firstly.
