The very act of seeing is sullying by nature.
Yes, the very act of observation affects the thing being observed.
To call it "sullying" is clearly not being impartial.
I am agreeing to this observation because it has been demonstrated on a quantum level. Like many QM effects, it is believed to hold on every scale level, including that of our own "macro" world. But the magnitude of the QM effect shrinks as the thing being observed gets larger. The quantum indeterminacy remains on a tiny scale. Therefore, it is widely agreed - and certainly by myself - that the physical "sullying" of the observed by the observer is negligible in the everyday scale of humans and things of comparable or larger sizes.
You've taken drugs, so you must know what I am talking about. Slight changes in the brain's chemistry can affect perception dramatically. This alone shows how dependent our experiences are on the structure of our sensory apparatus, nervous system and brain.
We can only observe what the stucture of our senses and brains allows us to observe. If we had different senses, different brains, a different size, a different time-scale, then the world we perceived would be a very different one.
Since it is impossible to perceive the world without sensory apparatus, and since sensory apparatus is necessarily limited and restrictive in nature, distorted perception is unavoidable.

Not as far as the thing-in-itself is concerned.
This is an undemonstrated assertion. One can arrive via logic that a thing as it exists in our consciousness is not the thing-in-itself, that there is a difference between subjective and objective realities. It cannot tell us how the two realities may be related. Logic equally can tell us that two subjective realities are not the same thing, by definition. It is similarly silent on how the two are different and how they may be similar. Any assertions to the contrary are simply that - guesses. For instance, any two sighted people will say "blue" when asked what color the sky is. Yet there is no way of knowing that if you were suddenly transported into someone else's head that you would not see the sky as what you had previously called "green" and the grass under your feet the "blue" you used to see in the sky.
And so what does this have to do with the unknowability of the "thing-in-itself?

You still side-stepped the question. Have you ever tried to remove a bent nail with a ball-peen hammer or a mallet? The limitations of
what hammer, David?
I thought your question was "whose hammer"? Whose consciousness?
Once we determine what a hammer is and recognize its inherent limitations, these limitations don't suddenly go out the window simply because of who happens to own it.
The basic limitations of consciousness are patently not "always" the same. Let's get a third opinion - let's ask someone in a vegetative coma. Oh, that's right. He can't hear you.
You're not understanding. You seem to have a problem with thinking about things on a fundamental level.
Yes, it is obviously the case that consciousness comes in all sorts of shapes and sizes, yet all of them, without exception, are bound by the limitations which are inherent in consciousness itself.
Just as humans come in different shapes and sizes, with a wide variety of capacities and skills, there are some things which are inherently impossible for a human to do. For example, a human can't exist in two different places at once.

By breaking the unnatural constraints you have forced upon it, you mean.
Well, what is consciousness, in your view?

Yes, but God is never built by man.
Very true. He is always built by women.

You are misapprehending the nature of things.
Take the existence of disease-causing mico-organisms. Humans recognized diseases, but not the germs that caused certain ones. People did not even suspect that such things as tiny living things too small to be seen existed. You will say that they had the potential of being observed while the thing-in-itself does not. Then tell me - what now has the potential of being observed but no one even suspects exists?
Any unpredicted event.
There is no reason to suppose that people today have uncovered every such unsuspected "subjective" reality, is there?
No one is arguing that.
In stating the obvious truth that the thing-in-itself is utterly unknowable, I am not saying that all events within consciousness are already known. We can only know and experience a small fraction of all possible forms, and being creatures who exist in time and space we have to wait until a thing is causally created into existence before we can experience it.
Suppose there is a subjective reality to the notion of a personal God? Again, what if God has created a multitude of unseen presences whose task is to observe without being observed?
Your logic cannot answer this or most questions.
What if God is a collection of small invisible turnips who love to observe humans from the vantage point of their back gardens? Without any credible evidence, your conception of God has no more validity than this.
