I don't believe I am, though I may be stressing the roots of agnosticism beyond their ordinary usage. But typically, when someone says they are "agnostic" they are speaking a shorthand for "agnostic atheist." rather than a pure agnostic. Agnosticism would entail that there is no knowledge-basis to determine whether or not God is existant, as a strong position it would require denial of the possibility but as a weak position it would be an empty claim. But it is commonly used to conceal the claim that is actually made in atheism, with whatever strength that claim is made by the person stating it. It is used to shield the claim "there is no god" from scrutiny, by absolving it of being a claim of knowledge.
On that part, I can agree with you. But from my angle, I would just chalk up such a form of stiff agnosticism to a refusal to look at further facts, further forms of evidences, additional methods and/or praxes, or for that matter, to simply engage robust sources that they have heretofore not engaged.
An instance of this is the fact that in several years of having a book list placed on CF, I haven't seen a single person take one single source listed, engage it, read it and attempt to throughly refute it to me. No one's doing that. And I have a difficult time believing its "simply" because they haven't gotten around to it. No, it's usually because they want a particular "EPISTEMIC FORM" of Christianity to be true............or bust. They want to have their cake and eat it too, and my sources, my viewport, my worldview doesn't allow anyone, even myself, to default to that epistemic position. There is no "Genie-In-A-Bottle-Jesus," and I'm only more than happy to make that known.... to everyone. The problem is that that is exactly the sort of Jesus so many people want. They want the Jesus who is going to hand them "bread" with not only no strings attached, but who vividly and easily leads them to Vegas Level Prosperity written large in big Neon Signs. When they don't get this epistemic form of Jesus, they bust. And that leads directly into the Secular world we now live in.
Sorry folks! That's not the historic perception, nor the reality of ANY Jesus I can conceive of as being possibly 'real.'
Likewise---and here's the upshot in this epistemic, existential position that I hold----I don't expect the same from science either. Modern science isn a pragmatic pie-in the sky, self-propelling dynamo that will achieve liberating, transhuman progess, guaranteed. I don't expect it to work that way, and when it makes promises that it inevitably will given enough time, I swear I smell an epistemic rat.
And I don't believe I am putting too much emphasis on the Cartesian trickster-god, because an agnostic would have no basis to believe that such a god does not exist. The implication of which extends to all gods worthy of being called supernatural in the strictest sense.
From my experience, agnostics are simply people who feel they haven't had their questions answered yet the way they want them to be answered. There can be many reasons, though, contributing to their peceived feelings on this.
In such a precise and technical form, the qualifier "approximate" serves little value. It can distinguish one naturalistic theory from another, but it fails to overcome the objections raised by antirealists by either being too weak through specificity or begging the question entirely.
Which is fine when we're distinguishing between one scientific theory or another, but not when we're discussing how to interpret the instrumental success of science.
I'm not a big fan of Pragmatism. Let's just agree that Science has Limits and that a lot of people don't seem to recognize this or ... believe it.
Beyond this, we're just bantering and I'd much rather engage the specific articulations of various PhD level theorists than play my own "version" of Philo-Hockey.
