[Rationalism/atheism] is [potentially dangerous]. It can [permanently damage the seeker's moral core].
We are dealing with fire here.
I'd love to hear an elaboration of this. How can rationality be so dangerous?
Perfect rationality is, by definition, perfect and can never go wrong, for if it went wrong, it would not be perfect rationality. But none of us is perfect. When an imperfect person comes into contact with this ultimate solvent of unexamined beliefs, the ways they could go wrong outnumber the ways they could go right.
"There is no such thing as morality, therefore I can lie and steal all I like and you're a chump if you don't!" "There is no afterlife, therefore all is meaningless and I should just cut my throat now! Or yours! It doesn't matte...
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
