I rejected (what I perceived as) its: aggression, abruptness, insensitivity, black and white view of the world, absurdly high expectations, refusal to admit exceptions to the rule, pushiness, lack of sympathy - how demanding, judgemental, prejudiced, bigoted, presumptive, dictatorial and unforgiving it can be. Now I'm not saying this is fair depiction of Te but that's how it came across to me, in part because my ESTJ sister has displayed all these unhealthy sides of Te in the past. Actually, my extended family is one big Te-fest.
It was more than I expected because I discovered all sorts of little things it did that I never really recognised or valued. I've just been getting different vibes from TJs than I used to. A lot of things fascinate me about Te but most are vague impressions that are hard to describe. One of the main things that fascinated me is its ability to cut through the BS and make worryingly or stressfully complex situations/ideas/questions into straight-forward answers. I used to think that there was no downside to complexity but Fi's inclination for this (especially Fi+Ne) can be so overwhelming. It wants to make everything so endlessly complicated that it renders the world into a place without a single solid piece of ground to stand on. Te's ability to sort through it all and say, "it's just ____"; to summarise so succinctly, to find meaningful truth and clarity without the if, buts and maybes can be so reassuring, so unburdening, so enlightening. I'm slowly learning how to do that. It's really helped me to stop getting buried in the complexities and just find something that true and simple in all the mess of life - even if it's just in a joke or silly comment. I can also see how much that can that quality can be supportive and helpful to others. It amazes me that a function I previous found so cold and heartless can be the bringer of such kindness; seeing how a TJ can so insightfully, sensitively and conscientiously help solve the problems of others in ways a Feeler would struggle to.
I guess I've just discovered the underlying beauty and elegance that exists behind the directness - and I always find it intriguing to discover new layers and unexpected positive aspects to familiar things.
This is what I used to think, but I think it's a limited view of it. It's like how Se is described as just being about the literal physical world; just seeing things as they are; living in the moment. The most enlightening and revealing description I read about Se was that it's "contextual". It's not about 'the concrete' or 'the moment'; it's about seeing things/ideas/experiences as specific to a time/place/circumstance/plane of existence/whatever. It's about keeping things separate and uninfluenced by extraneous data so that you view them with clarity, purity and an attuned awareness. So there is a sort of brilliance and complexity behind the relative straight-forward aspect of it. Same goes for Te.
