Aspergers and religion have an odd relationship.
In my experience, whatever Aspies believe, they tend to be really staunch believers. I don't think it's a co-incidence that some of the most religious people I've ever met, and the hardest hardcore atheists, have been on the spectrum.
Aspie and autistic pagans are more common than you might think. I'm active on a large pagan forum where neurodiversity is very well represented and there's at least two other active members on the spectrum, and I've also met other autistic pagans in the course of random online conversations.
All this proves that we come in the same range of religious flavours, from militant atheist to Christian to minority religions to utter apathy, as the general population. The distribution might be different - I suspect we might have more people at the extreme ends of the range - but overall we're as spiritually diverse and varied as any other randomly selected group of people.
While we're talking about religion, I'd like to mention the very old and sadly not yet entirely extinct idea that autistic people don't have souls. I don't know where this came from, but I suspect it's a hangover from the belief in "changelings", which is possibly an old folklore attempt to explain autism. By tradition fairies don't have souls, so changelings, being fey creatures left in place of the stolen human child, wouldn't either. Or maybe it's just some ableist horseshit. Either way, it's perhaps the weirdest and most bewildering lie I've ever heard about autism.
