So you want something serious to think about?
Thank you Dr Chinese. I appreciate your effort.

Here’s a tip, if you're relying on math to explain your thought experiment. What you have is a piss-poorly designed thought experiment.
No, I would say rather that your comment implies that you are not comfortable with mathematics. Let me quote Feynman, "mathematics is the distilled essence of logic."

One wonders at the stupidity of starting a thread with a thrown clock, then posting that in your system all clocks have to be at rest.
Not if that issue is the central issue I want to talk about. I want to talk about something which in your head is stupid! Ok, if you don't want to talk about it, don't bother me.

To me (and I presume to some others), you appear to be merely arguing semantics. The short form of your point, as I currently understand it, is "Physicists don't explicitly state things like 'in the clock's rest frame', therefore they must not understand that this clause is needed," which, frankly, seems silly.
Forty years ago I also thought the need to point that out was silly; however, over the years I have come to realize that it is exactly the issue which has prevented the physics community from seeing what I see.
My single greatest complaint with web forums is that the members never expose their education level. That makes it very difficult to cast one's comments at a level the reader can understand. As above, Oracle has finally made it quite clear that he really isn't comfortable with analytical thought. Now you haven't made your range of comprehension clear yet but, as you are apparently the only one reading this thread who has any comprehension of the real issues of relativity, I will proceed as if you have the background to understand a difficult subject.
I hope you have your thinking cap on. Earlier, I brought up the subject of parametric representation of space time lines. Though you have not commented on that issue, your general comments imply you understand enough to follow a presentation based on such a representation. I hope that is a correct assessment.
Let us consider a relativisticly correct solution to a problem. Now this can be an experimentalist's describing the results of an actual experiment or a theorist's analytical result of a hypothetical situation. In any case, accurately expressing the solution requires specifying the coordinate system of the real or hypothetical observer (the coordinate system or frame of reference within which the results are to be expressed). Now, if a correct solution has been obtained, then that solution can be expressed as a set of space-time lines in the referenced coordinate system (a specific line for each specific significant element in the solution).
Now I need to point out that the problem referred to here can run the gamut from the trajectory of a macroscopic object through a collection of massive gravitational sources to a QED calculation of fundamental phenomena involving Feynman's inclusions of virtual particles and the consequences of their impact on results. Even if the number of elements included the solution of that problem run to numbers far beyond what we want to explicitly write down, from an analytical perspective, the solution can be expressed as a collection of space-time lines in that observer's coordinate system.
We are talking about expressing information here. The coordinate system we choose to use, in the final analysis, is nothing more or less than a reference system used to express that information. So, in deference to modern physics, let us use the space-time continuum introduced by Einstein: the coordinates will be x,y,z and t. The signature of the coordinate system will be taken to be three real coordinates and one imaginary coordinate. Depending on the problem being solved, the coordinate system can either be a standard Minkowski space or, if general relativity is involved, the Riemann generalization of that space.
If that is the case, then the solution of the problem (and it doesn't make any difference what the problem is) can be explicitly displayed by a set of parametric representations of the space-time lines of the elements significant to that solution.
x_1 = f_{x_1} (\alpha_1), y_1 = f_{y_1} (\alpha_1), z_1 = f_{z_1} (\alpha_1) and t_1 = f_{t_1} (\alpha_1) --- entity #1
x_2 = f_{x_2} (\alpha_2), y_2 = f_{y_2} (\alpha_2), z_2 = f_{z_2} (\alpha_2) and t_2 = f_{t_2} (\alpha_2) --- entity #2
x_3 = f_{x_3} (\alpha_3), y_3 = f_{y_3} (\alpha_3), z_3 = f_{z_3} (\alpha_3) and t_3 = f_{t_3} (\alpha_3) --- entity #3
…
x_n = f_{x_n} (\alpha_n), y_n = f_{y_n} (\alpha_n), z_n = f_{z_n} (\alpha_n) and t_n = f_{t_n} (\alpha_n) --- entity #n
…
Now I presume, you will concede that all relativisticly correct answers to any physics problem could be so expressed. That is, all the information contained in the solution to the problem is contained in the set of parametric expressions above which clearly express the space-time lines in the relevant "approved" coordinate system applicable to the associated problem.
