I meant in the typology sense--that F/T are both Je/Ji (rational) and S/N are both Pe/Pi (irrational) but yeah I see what you mean. Though I think feelers are just as necessary as thinkers in the world, I appreciate both of them.
I know what you meant when you said what you said earlier. But being that I'm an Extroverted Thinking type, I have to "explain" things. I didn't think you didn't understand me, but it's just a habit of my type to go on and discuss the topic slightly further.
I don't know if Feeling types are "necessary" but there's far more Feeling types in the world than there are Thinking types. I've read it's about 75-80% of humans are Feeling types and 20-25% are thinking types. It makes sense, but it would be erroneous to mistaken Thinking types to be emotionless. Thinking types express their emotions differently, and they handle it in a more "concrete" manner than Feeling types. That's why I wrote what I did about thoughts vs emotions. I don't discount emotions as being unimportant, because emotions are important, but it is not factual and not rooted in reality, which means it's virtually impossible to share emotional experiences as they are deeply rooted in the individual, but thoughts are able to manifest in the material plane, which can then be "shared."
I don't have problems with Feeling types (as 2 of my closest friends are INFP/J), but only drawback I see with Feeling types is that they aren't necessarily concerned with anything manifesting in reality. However, more often than not, Thinking types will be concerned about how something gets executed. Just because ENTPs are idea machines and are devil's advocates, we will eventually test some of our ideas out and it will come into fruition. We're just not committed planners like ENTJ version. ENTPs aren't inventors for nothing. We do get around to achieving some of our ideas LOL Time and time again, me testing out my ideas have been supported by verified Thinking types and they even contribute by giving me their thoughts on my ideas/plans. Feeling types offer me their hesitations, but nothing of rational value. Although I appreciate Feeling types showing concern, I don't want or need anyone to be emotional about me or what I do. I do need more people to be rationally cooperative with me, and help me accomplish what I want to see accomplished, and then some!
However, the world operates on ESFJ sort of perspective. On the introverted side, the world will favor ISTJ. The most rare type is supposedly INFJ, which makes sense because such a combo is really ODD! In general, the world sees people who are Intuitive are, well, screwy. Extroverted Intuition types can handle the screwball label much better, but Introverted Intuition types have a difficult time speaking out and have a hard time rectifying their true identity with how the world identifies them. I love that most people see me as a screwball. It's hilarious and I give an evil laugh. But again, I can't say Feeling types are necessary, as much as they are abundant. I would say that Thinking types are more needed because we're the ones who have to fix up everything when things certainly will go to hell.
