I don't find it offensive, I just found those 15 things to be something that someone would ask or say if they didn't know much about autism. The thing about autism is that most people who aren't directly effected by it don't know much about it. Most people with AS who are out there working or socializing don't go around telling people they have it, so it's not something that there is a big "awareness" about and it's also not something that most people think they need to be especially on the lookout for in others - ie; a boss telling an employee that no he doesn't think it's a big deal that the guy three cubicles over plays his radio softly because most people don't even notice it, or people not being shocked when an adult who has always seemed "normal" has a meltdown or gets extremely agitated over something unimportant seeming.
I know there is a big push for acceptance and assimilation and I'm all for that, but if we start complaining and being offended over things that most people don't know not to do or say, right away, and if we come in with this big metaphorical laundry list of "You must do and say this and not do or say this or else you are discriminating" rather than educating people about the wide range of the spectrum, and letting them see that not every person who has autism is like the stereotypical low functioning child in a TV movie, all we are going to do is reinforce their belief that we are too obsessive, peculiar, and demanding and that we are just too much trouble to deal with. Yes, we need to insist on and also earn the respect of others, but that also means respecting the fact that the whole idea that an autistic person can do what an NT person can do is something that has probably never crossed most folks minds and it will take some time for that idea to become mainstream.
In other words, don't meet your new in-laws with a shaved head, covered in tattoos and, wearing a t-shirt that proclaims you are a Satanist. walking your pet tiger on a leash and then be surprised that they take some time to figure out that you are just a regular gal whose hair fell out after a bad perm, spent the day with your nephew who loves temporary tattoos, your washer broke last week and you were stuck wearing a tshirt that you bought during college for shock value and as a joke, who works at an exotic animal rescue and has to hand feed the rescue she took home. Especially if you immediately get offended and angry when are terrified of you as soon as they meet you.
Let's let people get to know more about us and what we can do before we start screaming that they are out to get us. While Autism Awareness has been around for a long time, it's still not all that big outside of certain circles. It's going to take some time. We only make it worse by being too sensitive over things that aren't deliberate nor are done with any intent to offend us. Let's keep the anger for the real bullies and bigots instead of helping to create more by alienating people right away.
