I've never been ashamed to be different, but have always felt different. Looking back, over the years, it takes a lot of energy to ignore all the external encouragement to change and adapt. In this context I feel the label deviant is appropriate, and even something to be proud of.
Today I read a new thread titled "Being conditioned to like Autism?!" http://www.wrongplanet.net/postt264994.html. I find the conclusion that the negative aspects of autism always dominate over the positive aspects somewhat depressing, and not generalisable, even if it may seem to be true from the perspective of certain individuals for potentially long stretches of their lives. I did not comment on the referenced thread, because the example it uses to illustrate autistics with a positive outlook on life is flawed and simplistic.
To understand and appreciate the positive side of autism I highly recommend the book "Through the Eyes of Aliens" by Jasmine Lee O'Neill http://www.jkp.com/catalogue/book/9781853027109.
From my personal perspective life feels like trying to catch a wave on a surfboard when you've started paddling 0.5 seconds to late. You can expend as much effort as you want, you never catch the wave. Good surfers learn to get the timing right and avoid the effort. With practice autistics can become good surfers, but at least in my case, I still waste too much time paddling at the wrong time.
When the negative aspects seem to prevail, the feeling is comparable to sitting in a sea kayak going downwind, where the waves in your back continuously push you onto the back of the preceding wave. You can paddle all you want, but you will never be able to push through the preceding wave. There is nothing you can do about it, and it's not even worth trying.
I think these feelings of wasting effort stem from autistic perseverance, and the tendency to always compete against our internal bar of standards in relation to our special interests, which we push higher and higher.
From experience I know that I have the capability of reaching all the goals that I set myself, if I am allowed to work towards these goals along the path that I chose, and if I don't have to explain every 5 minutes why I do things certain ways, or explain why I don't do them the same way as 99% of people would do them.
Hence in a social context, especially in a neurotypical context, the positive side of autism is always only one step removed from the negative side.
In concrete terms I have changed jobs several times because I could no longer take the insanity around me, and ultimately I ended up starting my own business, only to run into a new set of frustrations. On two occasions I have been offered to rejoin the corporate world in senior management roles, but in both cases I instinctively refused, because I can no longer live with the insanity that is at work in modern corporations. I think more and more people, autistic and non-autistic, are experiencing the insanity of modern life, and are suffering as a result. Hence my OP on being a deviant and being proud.
Currently I'm in a stretch of life where the positive side of autism has the upper hand. After more than 10 years my business has grown into team of 4 like minded non-conformists, and together we are able to complement our individual strengths. Relating this back to my special interest in water sports, I'm now on a windsurfer. The power of the team is like the wind in the sail, allowing me to ride over the back of waves, and even jumping over some of them
Still every day is a lot of effort, there are regular crashes along the way, but overall I'm sailing.
