I think you could have found a nicer way to make your point..... a better example.

In California autism rates have reached 1 in 88 (propaganda.... or real rate? Hard to tell. Nonetheless, it is high), and are steadily increasing all over the world.

This disorder is so prevalent now that when you speak on any issue at all, someone in your audience has probably been affected by autism.

Using traits of the disabled as some type of caricature example to espouse your unrelated opinions is not only unproductive..... but it also makes you look like a jerk.

I am absolutely NOT in support of a 'politically correct' society, but your example was in poor taste.
