I think you guys are sort of describing a continuum or possible things that can happen.
All the examples contain descriptions that are ring true.
It seems to me that on the more emo side you have:
1) an emo tantrum-you hurt my feelings about something dumb and now I am whining about it. Frequency-2X yearly
2) a cranky emo rant-I am annoyed by something around me and I feel a bit bitchy. I may get a bit petty and annoyed and may be bitchy towards another stupidly and undeservedly. Frequency-weekly to monthly
3) a sobbing emo spew-You have done something that feels very hurtful and you wont stop, even though I ask you to, thus I vomit out pain filled emotions at you in an effort to make you feel my pain. Frequency-only a few times in my life.
4) The insanely, hateful emo driven, but cold and viscous, slash and burn to another person's soul rant-In that moment I want you to make you cry. It is out for blood. The goal-who the fuck knows. Frequency-once in a lifetime, LOL.
These are all somewhat defensive in nature and seem to progress pretty slowly, but are emo leaky.
On the more rational, but value driven side, with longer term, well considered impacts in mind:
1) an idealistic, emo Fi tirade for what is right and true-I wouldnt say it if I didnt think it was legit. Frequency-a few times a year, typically via text or to other people I work with on issues I feel impact a large number of folks around us. Haha, in the past it involved emails to VPs. My emails are legendary.
2) The Te not-to-do list

This seems to be what Esoteric was talking about. In this case you have crossed a boundary and you need to have a very clear understanding of what it was. I still care for you though.
3) The dispassionate analytical critique of dissection. I find I use this one more and more as I age, as I dont really like expending the energy to get hurt about assholes. I could get upset, I could let them effect me, but mostly i ignore them. A doorslam sort of ignore. If they really bug me, I just start look through them, start meticulously dismantling them and sorting through the pieces and parts of their psyche. It is very distinctly NeTe but hyperfocused on finding holes and gaps in the person-it is still Fi driven, but Fi has totally left the scene of the dismemberment. I dont like myself when I feel this way, so I try to just ignore them as this method makes me feel gross inside. There is no emotion, just a cold sense of focused analysis.It is objectification of another person. If I externalize this on you, you have really crossed a large number of boundaries... We see things all the time that we never talk about-unless pushed.
