Nope.
Autism is too complex to be encapsulated in a single meme or bumper sticker slogan, so people aren't interested enough to take any time to understand it. It doesn't affect them personally, so it's not that important.
Even the people who claim to care about you will only superficially read an article or two and think they've got a handle on it. But you know when they say things like "well, if you'd just try a little harder..." that they haven't learned a thing.
But, can you blame them? You're talking about people to whom everything in life comes relatively easily, for whom communicating with others is a simple process, and anxiety just means a few butterflies before giving a speech.
They have no idea what it's like to walk into a shopping center and be overwhelmed by the tidal wave of sound emanating from the industrial air conditioners 30 feet overhead, and the incessant murmur of voices throughout the building, and the cacophony of electronic bleeps and bloops made by all the cash registers and infared tag readers - when they say something to you and you have to ask them to repeat it three times because you can't make out their words over all that noise, they just think you're mildly deaf or not listening, because they don't even notice all that racket. How could they possible understand what's happening to you?
When you can't leave the house or make a simple phone call because you woke up that morning with your stomach in knots (just a normal day) and the thought of having to think clearly while simultaneously interacting with people you barely know and the idea of keeping up a pointless conversation has your nervous system raging in fight-or-flight tension, but you're really incapacitated like a deer in headlights, and can't force yourself to move, beyond the uncontrollable rocking back and forth that keeps you from screaming out loud - all they see is somebody being stubborn and uncooperative, because c'mon, it's just not that big a deal.
And when you're pushed into a roomful of strangers, and you'd really like to maybe make a friend, or at least be accepted as a nice person with a working brain and perhaps something reasonably intelligent to say, but instead you find yourself standing in the corner, able only to mumble "hello" whenever someone speaks to you (not that anyone does) and looking desperately for an exit you can sneak out of when no one's looking, so you can go home feeling empty and alone again - they just see someone who isn't willing to try and who doesn't mind being perceived as antisocial.
They just don't get it, they never will get it. But it's not just because they don't care enough to bother - it's also partially because they aren't capable of getting it. It's all an alien life to them and they'll never once actually experience it as long as they live.
