I do agree that NT's generally have a fear of autism (just look at all those soccer moms saying that autism is destroying their families). However, the fear is based on the general NT fear in whatever they don't understand. In my experience, the more an NT learns about autism in general and the strengths it can provide, the more likely an NT will accept an autistic as he is. All of my friends know full well that I am an aspie, and are perfectly okay with it. In addition, I work at a church, where most of the people there also know about my condition (I'm fairly open about being an aspie, and am not ashamed by it), and again, they are not afraid of me or see me as some kind of "monster"...
Organizations like Autism Spoken For prey upon such fears in mothers, which is why they become so powerful. My own mother, herself an aspie, didn't give in to such fears... while she nominally supports stuff like genetic research that Autism Spoken For carries out (a point I've argued with her about multiple times), she didn't believe all the hyperbole that they were talking about (the whole thimerosol thing, for example), and instead of trying to put me through dangerous experimental "therapies" like gfcf and chelation, instead found a physician that knew specifically about autism (such a person was relatively rare in 1988), and got me some things that I needed. Instead of wasting all her time casting blame on some obscure theory, she actually put effort into raising me (and my lfa brother) up instead...
