it's a lot like AIDS. there's good AIDS and there's bad AIDS. Good AIDS is when you get it from a blood transfusion, the Doctor gives it to you to make you stronger. Bad AIDS is when you do something gay and so God punishes you.
Autism is the same way. Atheist parents sometimes give birth to a kid without a soul (Bad Autism). Christian parents sometimes get a blessed child who has special powers (Good Autism). Our Lord Jesus Christ himself had Good Autism. Good autism is good.
