few people would doubt that ASD is real, and that for most individuals it is a persistent condition, underpinned by complex and durable neurological differences that cannot easily be 'cured'. The same is true for being trans.
Interesting comparison of gender dysphoria to autism.
First - it is not proven that gender dysphoria is a neurological difference like autism, as opposed to a mental illness.
Neither can be cured - but the difference is that whilst autism will never be 'curable', because it is not an illness, dysphoria may one day be curable (if it is an illness).
Second - the more interesting part of the analogy is the requirement of the rest of society to make accommodations.
Few would argue that we should not make any accommodations to enable autistic people to take part in society. But these accommodations don't require half of society to be seriously disadvantaged.
Simple accommodations are fine - men can wear dresses and autistic people can wear headphones in the office.
If an autistic person insisted that all cinemas had to show all films with the lights up, the sound right down, and subtitles on the screen, they would be laughed at and ignored. If they persisted in their insistence, they would be told to seek out one of the 'autism friendly' screenings that many cinemas now offer.
Men with gender dysphoria who want to use women's toilets are like the autistic person insisting ALL film showings should be adapted to suit autism. The men with dysphoria should just go to the facilities meant for them (in this analogy, the fully enclosed unisex toilet is like the special autism screening).
And if an autistic person who doesn't like loud noise wants to go to a big rock concert but with the sound turned down, well tough, they can't. Likewise, many life experiences are just for biological females, not men with dysphoria.
