What a load of nonsense. I'm seeing people who are capable of coming onto Mumsnet and articulating themselves, complaining that a certain, helpful phrasing, which people may use for family members who will never have the capability to converse like this, minimises their struggles.
No. The fact that a person has reached the threshold of diagnosis at all means that they must struggle in day-to-day life due to their autism. This is acknowledged.
What it does is differentiate it from others who have autism. Yes, there are variations of presentation, but those variations can also be milder or more severe, while still causing significant impact as compared to people without autism.
So a person who has more extreme variations, or has limitations in areas that (for instance) impact them to the point that they are non-verbal, or need carers, could be reasonably described as having severe autism (or profound, etc).
Whereas someone who meets the diagnosis threshold but is able to function in society day-to-day in terms of caring for themselves, paying bills, buying groceries etc would be reasonably described as having mild autism, because it impacts them to a lesser degree than it impacts others with autism.
It's not about minimising struggles (obviously everyone with diagnosed autism must be significantly impacted) it's about describing the degree to which autism may affect a person as compared to others with autism.
Is it a hindrance that makes life difficult to manage, and can restrict one's opportunities? Or, is it a total barrier to ever functioning independently in society?
These are very different things. (And I say this as someone who would describe myself as having mild autism.)
