In that case, I struggle to see why the “defeater critique” wouldn’t seriously undermine practice (1) in most cases. Philosophers can’t simply assume intuited contents p and then move from p to q. We want to know how likely p is to be true, and if our primary reason for thinking p is true is some unreliable cognitive algorithm (rather than, say, hard scientific data or a mathematical proof), then we are left without much reason to be confident that p is true.
Suppose a theist says he knows by Holy Spirit Communication (HSC) that Jesus is magic. An atheist replies, “HSC is not a reliable method. See all this experimental data on people making judgments based on the deliverances of (what they claim is) HSC.” The theist then says, “No, I’m not arguing from the HSC mental state to the conclusion that Jesus is magic. I’m arguing from the HSC contents (that is, from proposition p) to the conclusion that Jesus is magic.”
The atheist would be unimpressed, and correctly so.
In the case you describe, the “HSC content” is just that Jesus is magic. So there’s no argument being offered at all. Now, if they offer an actual argument, from some other p to the conclusion that Jesus is magic, then we can assess this argument like any other. How the arguer came to believe the original premise p is not particularly relevant. What you call the “defeater critique”, I call the genetic fallacy.
It’s true that an interlocutor is never going to be particularly moved by an argument that starts from premises he doesn’t accept. Such is life.
The more interesting question is whether the arguer herself should be led to abandon her intuited judgments. But unless you offer some positive evidence for an alternative rational credence to place in p, it’s not clear that a “debunking” explanation of her current level of credence should, by itself, make any difference.
Think of intuitied judgments as priors. Someone might say, “There’s no special reason to think that your priors are well-calibrated.” And that may be true, but it doesn’t change what our priors are. We can’t start from anywhere but where we start.
What you call the “defeater critique”, I call the genetic fallacy.
Thinking of things in terms of informal fallacies like the genetic fallacy throws away information. From a Bayesian viewpoint, the source of one’s belief is relevant to its likelihood of being true.

Right; I mostly complain about arguments made solely from intuited contents when the claims are given with far more confidence than can be justified by the demonstrated reliability of human intuitions in that domain.

(Edit 9/2/13: A good example of this is here.)
