I think too many of us skeptics are skeptical about other people's beliefs, but non-skeptical when it comes to their own. To me, this is the real challenge of skepticism, to hold yourself to the same standards that you would impose upon someone who is promoting strange beliefs. I think this is the greatest payoff of skeptical thinking, to rid yourself of your own strange beliefs, but a lot of skeptics aren't willing to go this far. Some skeptics do admit they hold irrational beliefs for irrational reasons and that's probably the most that can be asked of them.
I agree completely. Unfortunately it took me many years to develop the ability to hold myself to my own skepticism. I believe that it is simply a matter of maturity. Both maturity in general, and maturity as a skeptic.
