I don't know if this applies to other Si/Ne types but I notice that some opinions and judgments I make carry different weights, and that the context that I choose to express it in is an integral factor in the strength or nature of the judgment itself. How I choose to voice the judgment (or the context I voice the judgment in) is a reflection of the level of conviction/annoyance I have toward the person I'm making the judgment toward. If I think someone is too fat, I'll feel "wow that person is fat", but it's more of an amusement kind of thing, and I'm not "angry" at the person and by saying it loudly with a certain tone in my voice would be expressing a different emotion and inaccurately reflect my level of conviction/annoyance on the matter.
I notice that when I'm talking with my Ti ESTp grandfather, sometimes he'll be like "Do you want it or not?" in response to me talking out contextual stuff weighing into a decision. Sometimes he'll be "Ehhh don't gimme that bullshit - you either like it or you don't" LOL.
In situations where the person is annoying me much more, l ike say I'm in a nice restaurant and someone is conducting business on their cellphone to the point where it's just so obvious they don't give a shit about disturbing other people around them, I may either say something about them really loudly to the people at my table so that the other person could hear anyway, or I may just directly talk to him myself. (In between the first and second option I'd probably talk to the waiters)
I'd say,"Hey pal rent a fucking office, no one wants to hear your loud annoying voice during our dinner". Depending on what ethnic stereotype he fits, I may add in a little comment hinting at cheapness and tailor it to fit his ethnicity.
But to get to this point - I would have to be fucking pissed. The point is, I have different levels of passion/conviction/flexibility with different opinions, and that affects how direct/forceful I want to be about something. If the guy in the restaurant was obnoxious for a little while but then stopped, I may say something sarcastic to the people at my table about how the guy is too cheap to rent a fucking office but buys and sells diamonds (I assume you know what I'm getting at
).
If he happened to hear and got offended, I don't care, because it is what it is - it's not my fault he's affirming a stereotype.
I wonder if this is a thing with Si/Ne types, where we don't have as much of an absolute approach to voicing our judgments. I have noticed with Betas that they just say stuff, what's there in raw form. Actually the overall tone seems consistent when they voice stuff, whereas Alphas' tone seems to be adapting their delivery to the external context and the intensity of the wave at the time.
I do believe in expressing how you feel, and there really isn't an excuse for "oh I was just messing, therefore what I said doesn't count" because you said what you said and the opinion came from somewhere. If you wanted to clarify in a situation where you made a "light-hearted judgment", I suppose you could say "Yes I am surprised by how fat you are, is there a problem?"
I don't know if the sort of "hiding behind" occurs more with Deltas or if there are other factors like enneagram that contribute. I notice that my 9w1 Fi ENFp dad will make politically incorrect observations of things but hold back from expressing them in certain public settings. For example one time when me, him and my two brothers (Te ESTj and Ti INTj) were out for pizza around Christmas time or w/e, the pizza place was decorated with Christmas ornaments. I think I said something like "That would be stupid if they had to put a menorah there too just because there are so many Jews in the neighborhood", and my dad gives me this face like "Heyyyy shhhhh - people can hear". My Te ESTj brother echos this same sentiment. Whereas my Ti INTj bro and I are like "So what? Let them hear - that's my opinion!". I notice this happens a lot when I or my Ti INTj bro have opinions that go against the "established norm of political correctness of what's acceptable to say in public". Either my dad or Te ESTj bro get this sensitive face and tell me to tone it down". When I ask "Who cares if people hear me? Why do I need their respect?" He doesn't answer - can't give a reason, he just gives me that "I should know better" face.
My Ti INTj bro, when he sees them giving that hush hush response, actually raises his voice so that he is more audible, AND emphasizes the words that he knows go against my dad and other bro's sense of what's acceptable to say in public.
