It's quite a garbled and confused piece. Very poorly written. It doesn't explain what the male and female traits are and assumes the reader will automatically know what traits the writer is referring to. The explanations given are also bizarre and inadequate in explaining human behaviour.
All human beings are socialised from an early age into roles and stereotypes based on sex (there is a biological basis for this but a lot of it is also cultural/traditional).
Humans are also socialised from an early age into other kinds of cultural, religious, tribal and traditional values to fit in with the communities that we live in - our manners, our clothing, our language, accents, what we eat and how we eat, and so on. We aren't consciously aware of how we pick these things up. Some of this is taught explicitly - like parents teaching young children how to use a knife and fork to fit in with general western culture, or learning to use chopsticks if you live in East Asian cultures, or learning to use your hands in South Asian cultures etc.
But a lot of stuff in human cultures is implicit and neurotypicals seem adept at picking up these 'unwritten rules' and social mores and adapting their behaviour accordingly. They absorb ideas about how the sexes might behave and dress and interact with one another. No one conforms to all the expected rules and stereotypes for their sex, but it seems many neurotypicals eventually find a balance they are comfortable with - they adopt norms they are ok with and avoid ones that they don't particularly like. In fairly liberal and free societies, people are able to do this without any severe penalties or consequences thanks to past efforts to build a more tolerant and accepting society.
The difficulty that autistic people have is that it's very hard for us to understand and pick up on the myriad subtle and implicit rules and norms that are established in any particular society. It's not that autistic people entirely escape socialisation - they are also influenced by it. However, in many aspects of life, unless it is explicitly explained to us why something should be done in a particular way and if it makes sense, then an autistic person might not realise there are societal expectations around certain activities, behaviours, clothing, hobbies etc.
On the positive side, it means many autistic people are quite happy being different, they approach life from a different angle, wear what they like and enjoy the things they do even if it makes them stand out.
On the negative side, it can have a significant negative impact on the autistic person as they are acutely aware of not fitting in from an early age, finding themselves caught up in misunderstandings or inadvertently confusing/upsetting people, they are more likely to be bullied because they stick out from the crowd and so on. Add on issues like sensory stuff and it's unsurprising that many autistic people feel uneasy about themselves, their bodies and their place in society and might have great difficulty in reconciling with all the loaded expectations and rules that permeates every human society. Some may settle on a 'trans identity' as a way of explaining to themselves and others why they are the way they are. And if a society is more 'accepting' of a trans identity rather than allowing individuals to simply be themselves, then the temptation to adopt a trans identity is even more appealing.
