I recall giving a presentation myself using powerpoint back when AFF was first starting in a special needs school to a bunch of aspies who had been spoonfed doom and gloom.
I started off with this:
And then asked "what is wrong with this blood?"
A few people responded "aspergers?"
I clicked onto the next slide and gave information about sickle cell, pointing out how it mainly affects black people.
I then asked "should we cure sickle cell or black skin?" and compared this to the negative traits of autism being like sickle cell - but that you would not need to cure autism itself in order to remove these negative traits.
Further, I then expanded on how special interests can be a positive asset.
Try a similar approach at first, and then if you wish show some of the horrors that curebies have caused - such as the numerous child murders and ABA, restrictions of our rights etc.
