It's huge and glaring procedural bias. Yet for those who engage in it, it's blinding.
You made that claim already, and it was rebutted. If you don't care to address that rebuttal with counterargument of your own, that part of the debate is over. Debate ends with the last plausible, unrebutted claim or argument. If you wish to revisit the issue, I'll gladly field whatever you have to say about my argument and the specifics you provide for why you think its flawed.
Because it renders any evidence that does not fit into their preferred method of drawing conclusions, moot.
Critical thinkers don't ignore evidence. There is no evidence that does not fit into critical thinkers' preferred method of drawing conclusions, which is to evaluate all relevant evidence for its rational implications. When they reject unsound conclusions drawn from it, it's because they're unsound.
It's a choice that serves the ego and protecting "belief"
It protects from false belief, which is what makes the standards for critical analysis a rational bias to apply to questions about what is true in the world.
I think what they mean is that there is no evidence at all
I don't.
it puts them in the "cat-bird" seat. Allowing them to presume that all proposed evidence has to meet their subjectively determined criteria for what evidence even is, or they can reject it as not being evidence at all.
It does. All argument has to meet the criteria of critical analysis, but it is not subjective. The method reliably generates correct ideas, and no other does. The only other method for coming to belief is faith, belief by which I consider irrational and subjective.
Yes, I see it happening often.
What I see happen often is you and others making claims for some other way of knowing that reveals to them (in their words) spiritual truths, followed by them being able to name any when asked. That describes you, too. You imagine some better way of knowing without which others are blind, but can't show others a single one of these wondrous sights he sees and truths he learns. Moreover, when I look at the lives of people who think like that, they're unenviable and undistinguished. They don't seem happy or at peace. Many seem to be endlessly searching for something that they never find, and consider that a virtue.
I chose a different path, and am quite content with that choice, which is why it always seems like hubris to me when others are suggesting how to think instead as you are. Why do you presume to have anything of value to teach to others? Where's the wisdom of your words or the magic of their rendering in your life? Have you accomplished your goals? I have. All I ever wanted was a life characterized by love, beauty, respect, purpose, achievement, satisfaction, and leisure in the absence of anxiety, guilt, shame, remorse, fear and insecurity. I have zero incentive to try out what you recommend, and no reason to think that your advice wouldn't be bad for me if I took it.
Where would I start? With a belief in hell? Or angels? Or magic?
What for? For the world to make more sense? To make it seem more significant? To be able to navigate it more successfully? To feel more connected to reality?
Have you noticed that I never try to give you life advice like you do others despite feeling that I found my answers long ago? Why? You didn't ask for my advice.
That we can ask the question, "Does God exist?" but we cannot answer this question, demonstrates that it is logically possible that God exists.
Why would that matter? Do you think not being impossible is a reason to believe? If so, why stop there? Vampires haven't been shown to be impossible. Shall we go get some garlic, or should we wait for a better reason than "not impossible" first?
All our arguments are arguments from ignorance.
You're going to have to speak for yourself here. I never do that, and neither do most other experienced critical thinkers. I'll leave that to those who think that if gods haven't been shown to be impossible that that is an argument that they exist. That's an ignorantiam fallacy.
Science cannot investigate anything beyond what physically exists. And yet even the universe itself shows us that there is more to it then that.
That's a self-contradictory statement. The universe doesn't show us anything that isn't physical. You're claiming that physical evidence is evidence that there is more than physical evidence, which is an incoherent comment like married bachelor or belief via a combination of evidence and faith.
Nothing posited to exist that is also said to not manifest phenomenally, whether directly like the sun does or indirectly like dark matter does, deserves a second thought. That defines the class of unfalsifiable statements about unseen alleged realities - the ones that make not testable predictions - which are neither correct nor incorrect, but rather, "not even wrong" and fit to be dismissed without further consideration in accordance with Hitchens' Razor.
