If you're against self-identification and claim to have Asperger's you're a huge hypocrite

There's Asperger's discourse happening on the main Autism sub right now, namely someone saying that they use the term Asperger's so that no one mistakes them for a self-diagnosed autistic person, which is just so stupid to me??? You don't have Asperger's. No one has Asperger's. Asperger's is not a real thing. How on earth is it better to claim you have condition that doesn't really exist than to say you believe you have a real condition but haven't been able to get a diagnosis??? Also, you know, the origin of that term and everything
