"I've asked at least a dozen times what the reasoning behind Decision 20-3a/2 and the USGA position that the cheater line is legal, despite Rule 8-2b, despite rule 14-3, despite Decision 14-2/4, despite the tee definition, despite the fundamental skill of aligning yourself from an address position, despite the fact that they banned croquet-style putting ...."
Shivas:
And I've answered you a number of times. Apparently you just don't want to see it.
The reasoning behind Dec 20-3a/2 is that a trademark (a line) used to align the ball for the purpose of indicating a line for putting does not constitute assistance in the act of making a stroke (Rule 14 is about "striking the ball"---ie making a stroke).
"... and all you ever say is "they disagree"."
Yes, I have said a number of times they disagree with you and your assumption that these things constitute a violation of the Rules.
"Well, no shit they disagree."
No shit, indeed. I think it's patently obvious they disagree with you and your assumptions on this thread that you have based your premise on that an identification line on a golf ball used to align the ball for the purposes of indicating the line of putt is a violation of a Rule of Golf or contrary to a principle of the Rules of Golf.
The question is "why?" What is the reasoning?"
See above.
"The only reasoning on this topic is in Decision 14-2/4 and it argues against the cheater line."
I see nothing in Dec 14-2/4 that's analogous or applicable to this thread's subject.
"So what's the principle in that golf bible that they all keep under their pillows at night that is soooooo powerful that it overrules all this other stuff?"
Again, there is no principle I'm aware in Tufts or otherwise that over-rules "all this stuff", as you call it, because there is no Rules violation here and there's nothing in what you call "all this stuff" that is contrary to any Rule of Golf or Principle of Golf that I can see.
Can you understand what I've said here---that your assumptions are inacurrate and therefore your premise that an identification line that is used to align the ball for the purpose of indicating the line of play does not constitute "assistance" and is therefore not a violation of Rule 14 nor a violation of Rule 8-2b which quite clearly contemplates a "line" other than on a golf ball?
