Asperger's is a syndrome, not an insult. On the internets, though, it's often used as a way to point out someone's unacceptable inability to understand irony, hyperbole, or priorities and degrees. Ludicrous behavior like that is what is meant by Asperger's (when used on the internet), not so much an actual claim about a disorder only a psychologist can diagnose.

While this may be true in some corners of the internet, that doesn't make it right, nor does it make it acceptable here. I am no expert on the rules here and not a moderator anyway, so obviously that's a matter for the mods to decide.

However, I will say that just because many people consider it acceptable doesn't mean that they should.
