Asperger's "murky past" is a completely fake modern hit-job.The murky past of Hans Asperger seems to be one reason for the move away from the term Asperger's syndrome. The term syndrome is also loaded.
It's not even clear why it was originally done, or why it survives, unless perhaps it was part of a wider program.
FWIW I use Aspie, but I rarely bother to tell people. It's really difficult for NT's to understand anything about ASD, to the point that a simplifying falsehood is better than an accurate explanation anyway

I agree with Outdated about words like Disorder or Syndrome.
