Mike Zubrowski makes some good points, but I think he is mistaken in his understanding of my argument. When I referred to 'brain wiring', I was not describing something that is determined entirely before birth.
While brain science still has a lot to discover, it has been clear for some time that many neural pathways are established in the early years of life and can also be affected by later trauma. This is the reason why, for example, a young child who learns a new language will be able to pronounce it correctly whereas someone who learns a language in later life may not be able to.
So my argument about 'brain wiring' is consistent with Mike's observations about brain development in a social and environmental context.
The understanding of 'neurodiversity' that we need is previsely about neurological variation in the context of social structures and our interaction with them - a materialist approach to neurodiversity.
