PhilCommander firstly thanks for posing the question in such a way as not to offend. I read monastic's reply and was thinking "Yeah right on...what next...yeah very good point...what else....yep!", etc
Basically they have nailed some very good policies for dealing/understanding austitic people.
I have mentioned this in another thread but I will mention it here.
My closest friends know about my Autism. I am 36 and high-functioning, which in effect means that I have had 36 years to develop useful strategies to hide or mask my Autism. I also compete in the "Neuro-typical world" quite well. What this means is unlike my childhood, teenage years or even young adult years, I respond better from learnt experience to certain situations better than I used to. I am and will always be Autistic. I make no excuses for it.
1. I am autistic and will always be autistic. There will be times that my behaviour will be not "normal". This will not be through lack of effort on my part - I assure you.
2. I am not looking for sympathy or even empathy of my condition - understanding is nice but tolerance is appreciated.
3. I am not stupid if I don't get an abstract concept. I studied at university level, creative writing - I excelled in the art, but not in the appreciation of the finer concepts of subtlety. I know what sarcasm, irony, analogy, similies and the like are, I just don't get them in practical application.
4. Understand that an awful lot of communication is through either body language, inflection of the voice, recognition of social cues or conventions or visual cues (doubly important for courtship!) - Autistics get barely any of this. I personally get very little of this if any of it.
5. We feel the world differently to non-autistics (very literally). We are more than not hypo or hyposensitive to various stimulous that a non-autistic person is not. Personally tactically I am weak (Hypo sensitive). I require a lot more stimulous to feel the same as what a non-autistic person. Example - pain. I have a high pain threshold. In fact I think to equate hyposensitivity to pain as having a high pain threshold is probably a little incorrect. I do not really register most incidental pain. I do in no way, and have never, viewed this as a positive - macho, blokey, tough thing, but rather as a weakness - in a kind of clumsy, brutish and oafish way. Kind of too stupid to realise that you are bleeding from a wound you ought to have been smart enough to realise you had sustained. (Not fair - its not my fault I know - but grow up in ridicule and the self-talk...)
6. OK you said 5 but this is important. No two autistic people are alike.
you have:
1 - different clusters of different traits (and some of these traits may even be hypo- or hyper- <as above>

2 - different levels of intelligence, from mental retardation to genius
3 - Different forms of autism
4 - Different levels of functioning (eg. high or low)
5 - You can also be severally autistic, moderately autistic or midly autistic
6 - Autistics quite often have co-morbids (Dyslexia, ADHD, Depression, Anxiety Disorder or other disorders)
7 - Different life experiences and Cultures.
Hope this helps!
