EDIT: please, if you don’t agree with the arguments in the video, come in and discuss, don’t just downvote the thread.
I found this video with many arguments supporting self-diagnosis validity and wanted to share.
Main point may be that there is no valid reason to look for a self-diangosis than the fact of being autistic, and needing support for that. At least until there will be equitable access to medical care, self-diagnosis is the only way for people to understand themself and understand the support they may need in their life.
But, there is much more in the video, take a look at it by yourself!
You sound like a language prescriptivist, you should look into descriptivism.
Let’s make deal, I look up whatever that is and you go study about autism spectrum desorder outside shallow social media posts, how does that sound?
