I still refer to myself as an aspie because it makes me sound smart, but I know it is in fact no longer a recognized term. Just as well, because I'd be somewhat of a weird cross between "Aspergers" and "classic autism" in the old standard. The current system, where it's just "autism with/without intellectual and/or language impairment" works well, and sums things up nicely. When you really think about it, the only real difference between "Aspergers" and "High Functioning Autism" in the old system was that people with "Aspergers" had higher than average IQs and no language delays in early childhood. Things have progressed, and IQ is measured in a much different way, negating these distinctions.
But the main issue I have with the term "autism" is that people have turned it into an offensive loaded term synonymous with "ret*d", and if I describe myself as "autistic", people will think I'm insulting myself. On the other hand, as soon as you mention Aspergers, people start thinking of Sheldon Cooper (and in years prior, Gregory House). I think these two characters are awesome, personally, and it is kinda flattering to be compared to them, but I can see why this would irritate some people. In either case, both have become somewhat "loaded" terms, which is very unfortunate, but it just so happens that one's way worse than the other, so I use the one that makes people think of lovable TV characters.
