The only way I can see justifying the "narc first, negotiate later" approach is if I don't expect the "negotiate later" part to ever happen and am simply seeking to be a vindictive jerk and want to cause problems for them.
No, I am asking you to engage with the argument in good faith, and making some token effort to understand what the argument actually is.
And it should be obvious, to you, if you do engage in good faith, that the "simply seeking to be a vindictive jerk" is not the reason anyone would have to make this argument.
