I think the ultimate issue is that those with autism will find themselves without a voice in the issue and then will not be able to make the choice themselves. Either the Neurodiversity side will effectively stop a cure or if a cure is found, the government, to save money, will force it on the entire population.
The real problem though that is being ignored is the quality of life issue. If a person could be accepted in society for the way they are, think, act, etc within reasonable guidelines (we should not accept the actions of a convicted murder), then their life would be better and they would not want a cure. However, it is no more our choice to deny the person interviewed in the article a cure than it should be choice of someone else that we should be cured.
