Perhaps he blessed with a superior intellect, or just indignation. He has declared himself to be a skeptic, and Hal as well. Based on that assertion, he argues that it is therefore possible to be a skeptic and a theist.
To be fair, Hal is a deist in the most restrictive sense. There's precious little to examine about the claim of deism. Assuming Cleon's religious belief is of the same stripe, then the argument that one can be both a theist and skeptic has legs in his case.
Still, ain't no one perfect. I'm sure there are things I believe which are bunk. However, I agree with you that it's very odd to watch people with one religious belief critically and skeptically examine someone else's beliefs. It's a little kooky to me.
Yes, I agree, I've believed things as well that turned out to be bunk, and I probably think I know things now as well that is really bunk, only I haven't heard about it yet. However, when I do realize it is bunk, I discard those things. That's what it is about to me, not being perfect from the get go.
And yes, the last you say is what is puzzling to me, and I have merely stated here that, just as you, I find that a bit kooky.

I think that all of us that do wonder about this are not arrogant in the least, and in no way have we said we think that people like Cleon should not go to TAM, work for spreading reason, and all the other things he mentioned. Why on earth would we say that?
As I understood it, this (the OP and all) isn't about what theistic skeptics should or should not do, they are free to do what they want, and personally I think many of them do a lot of good here (as I said before) but that it is essentially about the very definition of the word 'skeptic' and what that entails. That discussing this generates a reaction such as Cleon's does come of as a wee bit defensive to me. And for no reason, he doesn't have to defend the way he is, because it is not under attack. And he has not replied to those who really raised some valid questions about his first post in this thread.
My personal definition of the word skeptic makes it incompatible with religious beliefs of any kind, though I have said that I am unsure as to what the "official" definition really is, and I have therefore not declared anything about how others should think and act.
