How is Asperger's syndrome relevant to the 'hiddenness of God' question?
Having difficulties in communication is relevant for most, if not all questions anyway.
Whether those difficulties are due to deafness, blindness, not understanding the language in which the other person is speaking, being under the influence of intoxicants, exhaustion, or psychological deficiency.
Returning to the subject of this thread, how is the ability to read, model and react to other people's psychological states relevant to the 'hiddenness of God' question?
In a similar way that the ability to read, model and react to other people's psychological states is relevant in most other things in life, from eating to working to bungee jumping to sleeping.
A crucial factor of maturing, growing up is to be able to read, model and react to other people's psychological states, and to develop a measure of self-sufficiency, self-reliance, autonomy in regard to these.
One cannot drive a car or work, not even eat without developing a measure of such autonomy. Of course, we get some training in some areas of life (such as driving a car, some kinds of work, personal hygience etc.), which makes them easier. But, notably, getting a training in theism appears to be much more rare, and requires more effort on all parties involved.
And what justifies the implicit suggestion that those who disagree with you might likely suffer from psychiatric illness? That just looks like an insult to me.
Speaking of suggestions: How about when atheists suggest that those who disagree with them not just might likely, but very likely suffer from psychiatric illness? So much for insults.
