ugh, these things piss me off.
You know why more people are being diagnosed with autism? Because we've expanded our perspectives on what autism can mean, beyond the realm of 'low functioning' classic autism. Now, more girls, thought to be simply 'shy' can get that diagnosis. Now, I know handfuls of adults getting diagnosed in their 40's and 50's, finally getting an answer for why they've always existed somewhat differently than neurotypicals.
It's not as simple as 'oh, doctors overdiagnose autism'- tell that to the parents who fight to get their high functioning child diagnosed and get them receiving educational services. Tell that to the adults who beg for a diagnosis and don't get one 'because it's too late to do anything, anyways.'
I wont even TOUCH on the complete BS that autistic / neurodiverse people are 'brats'- I think it's enough to simply say that pisses the heck out of me.
