I'm not sure that it's really all that ignorant to be honest. I mean, when I explain things to people, most of them can relate to some degree or another. Almost everyone has things they do when nervous, or feels awkward time to time, or says the wrong thing in situations, etc. It's just how extreme it is that leads to the diagnosis.
*shrug*
Since I am not others, I cannot tell, of course, how much it really effects their lives, but they are able to relate to some extent to me. Some are very organized and go ballistic if that is messed up, some people hate plan changes, some people have a lot of quirks, some have collections of odd things, or obsessions. Not many of them are diagnosed, because they can move on from one thing to the next, or adjust when they realize it, or cope with it better than I do.
There is still a blockage in a lot of areas for full understanding, but it is rather interesting at times when observing others, just to try to gauge why I am the one diagnosed... and to try to figure out exactly how much more extreme I am with things-how much more do they effect my life vs. how the same things effect someone else.
A lot of people have some really quirky habits, but are also attuned to the world around them, and are aware of what is acceptable and what is not... so they are able to stop themselves. That, is what sets me apart a lot of the time, it seems. If I try to watch what I'm doing all of the time, I get worse and worse at dealing with things, and my ability to cope quickly deteriorates the more energy I use to try to keep it under control.
But some of the most interesting people I've met, the most fun, and the most accepting, are also the most bizarre in many ways around me, but not the slightest bit around others. They are able to mask it, able to control it, and are able to blend in with no problems.
