Rick,
This last post presents no evidence. It is the response of someone who is backed into a corner with no means to defend their position other than by lashing out. It is an emotional response and I would expect more from you. Take a breath and get back on point.
From what I can tell, you have tried to make the case that it is wrong to draw phasors with a neutral reference. You have been presented evidence that is contrary to that position. I will say now, and have in the past, that there are times when it makes more sense to draw the phasors in one direction. Coulter's working of the simple resistor circuit showed that to be true in that case.
It appears you fail to accept is that there are times when it is perfectly valid, and not "poor engineering" to use the neutral as a reference. I find accepting only one way as restrictive and, to put it bluntly, shallow. Winnie presented some fine examples of neutral references. There are many times when it is a common practice by engineers and technicians alike to use this method. I have provided examples in circuits and metering where this is the case. Drawing resolved voltage and current phasors can also produce these results.
The evidence shows that it is perfectly valid and reasonable, in some cases, to draw the phasors directed away from a neutral point. This fact is undisputed. It has been a part of engineering work since before you and I were born.
The mental giants of our industry found in the 1920's and 1930's that using a neutral reference point was very useful in the method of symmetrical coordinates/components. For you to come along almost a century later and make the claim that it is "poor engineering" to use a neutral reference is just ludicrous. These pillars of our industry realized that phasors can be drawn in either direction. The choice of direction is dependent on what you are trying to do. Calling one way the "correct way" and another the "wrong way" is utter nonsense.
Also, you have yet to validate the "nodal phasor diagram" idea and why it makes drawing phasors away from a neutral "wrong" or "poor engineering".
As far as what it is like to argue with rattus, I could not tell you. He has said some things I did not agree with in the past but I have not found myself having to argue with him, yet. I put forth the effort it took to try to understand what he was saying instead of trying to catch him saying something wrong. Maybe the sidestepping is an attempt to get you to try to get what he is saying by looking at it from another perspective.
I have not been here long enough to be party to all of the past arguments but I will say this: if we track what any of us say over a long enough time, you will find something stupid said. This is what makes us human, some more than others. We all get emotional at some point and say things we probably shouldn't, but who can throw stones? Hopefully, we will all be here for a long time as we all bring value to the table but we will have to overlook the times we step on each other's toes because it is bound to happen.
That being said, it certainly can be entertaining to spar with someone over an opinion. It can also be a good exercise in communication skills, so it is probably not a complete waste of time. Just try not to confuse fact with opinion.
