I fought my mom on any number of things she told me to do, but only once for each thing. When she, in the course of the argument, finally managed to (accidentally, in most cases) explain her reasoning, I was fine from then on.
If only all gifted children behaved in this manner. Or at least mine. I can promise you that in at least one family, with at least on PGlet, this was not how it went down.
I can certainly imagine that while teaching children in school, you would have such great results with being logical and respectful that you would think it's a sure-fire winning approach. If you had been my son's teacher, it might well have worked in the classroom. But I can tell you that the day would still have been draining (although delightful and wonderful as well) for my DS when he returned home, respect and logic just wouldn't be enough to get that 2 way street or respect going.
I do think that you are uncovering so excellent general guidelines.
1) With everyone, including one's children, try respect and logic first.
2) Observe the person's response, if respect and logic are flowing back in one's direction, then continue.
3) If respect and logic aren't flowing back in one's direction, try plan B.
