I completely and wholeheartedly agree. It's depressing. The autistic community has a very distinct voice and opinions about things but society is not always willing to listen.
For example, the vast majority of autistic people I have encountered in autistic advocacy groups are against the use of ABA therapy and deem it as abusive.
The majority prefer to be called autistic rather than 'person with' because they feel autism is a defining feature of their personality and they are not ashamed of it.
They don't like functioning labels because they make such broad assumptions about people abilities which don't necessarily help. For example, people are categorised as either 'high functioning' and therefore are expected to just get on with things with little support or accommodation, which often leads to high anxiety and depression or 'low functioning' which makes people expect very little of them and completely disregard their abilities and potential. I am in a Facebook group for AAC users- it comes up time and again that they feel they are treated as stupid because they are non-verbal, and that society would prefer to either force them to speak or for them to remain silent rather than accommodate their use of a computer to communicate.
Autistic people tend to subscribe to the social model of disability - that rather than trying to make the individual to 'fit in', society should be more willing to accommodate difference.
They don't want an 'awareness month' each year, people are already 'aware' of autism. What they want is more acceptance and more understanding.
Autism is a life long condition, it is a defining feature of someone's being. Being a parent to an autistic child is hard, but acting like autism is a tragedy and a burden, does not help your child. Listening to autistic people and trying to advocate more for acceptance in society might.
