chips, this really does sound EII to me, and not LII. i think i've mentioned thinking EII for you in the past too. i've had a hard time seeing you as LII, because i never see hard Ti analysis in your posts. your communication and verbalization is usually more Fi-oriented, you seem confident in making Fi evaluations and acting upon them (as you describe in the 1st paragraph in the quoted post), and you always talk about "relating" or "not relating" to things. also, i see you often asking for feedback, seeming unsure about your ideas and conclusions (weak Te). i think LIIs tend to be much more sure on their opinions about such things - they don't need anyone to "confirm" their ideas (not that they won't talk about them with others). and you're right that LIIs don't typically display the kind of sensitivity you mention. there's a reason why IxTx communication style is called "Cold-blooded"
it also sounds like you'd be an Oldham Sensitive type, which i would guess tends to correlate more to the Sincere (IxFx) communication style.
