Yes, this is kind of what I was waiting for. More Fi (and Fe) doms. My experience with ESI, with their creative Se, is that they will meet you on your level, whatever it may be. Even the most "high minded" ESI will not let you insult them and get away with it, unless they are depressed or something else is going on and they can't be bothered to respond. An EII I know will as well, if she is in a particularly bad mood or you threaten her family. Otherwise she tries to maintain calm and use a soft voice at all times. She is a 9.
My ESI, ex roommate, (I was maybe 20 at the time) was once described as bull in a china shop if you made her angry. She was great to have around when I was being more diplomatic and playful (read intoxicated and silly) when trying to deal with obnoxious jerks in a club. She would basically step in and tell them to fuck off me. Pulling me away or even pushing them away if she had to. I was pretty relieved when she did. She never let people take advantage of me when we were young, even though she was a couple years younger than me. I was basically raising her. We actually worked well together before I got a bf who came between us. With some people she would tell me, "you handle this".
My ESI aunt would absolutely yell back and then continue to rant about the person for a long time after.
If someone yells at me when I am driving I will also match their energy, if I'm in a bad mood. I don't yell though. I get self conscious when I yell because my mom was a yeller when we were kids. I didn't like it when she did it so I try not to do it. I will respond to them with gestures, facial expressions and some driving maneuvers of my own.
I probably get a bit more stubborn and refuse to meet their request right away. I take my time. If I am in a good mood I make fun of them and make a bit of a a show laughing at them then shrugging my shoulders. Thing is, it is likely that they will ruin my mood if I am alone in the car. If someone else is with me, and they are a chill or upbeat person, I don't get so irritated and my Fi stays in check. I will maintain the energy in the car rather than let an idiot driver ruin it for those with me. I have also been the one to calm down someone in my car when I thought it would escalate while we were trapped in traffic or something. I didn't want my friends going to jail or getting shot over something stupid.
My IEI brother is a bit different than me. He will say something goofy like, "oh yeah, fuck you too buddy". I am more likely call the an idiot, if I actually have an opportunity to say something to them (windows already down).
An EIE-Ni I know is more likely to yell back but not exactly match the other person's energy. They can sort of dominate it. They do it with a flare that I can't. It has some force behind it too but they do it in a more playful way. Like asking the person "what's the matter, baby, you got a stick up your ass?" I don't have much experience with EIE-Fe.
My ESE sister is probably the one pissing off other drivers but not intentionally, usually.
It is the way she drives sometimes. She is pretty good at handling drunk people since she is a bartender and her Fe is very useful there.
So many different ways Fi and Fe can be expressed.
