Your opinions please...
Mine is that a conflictor isn't necessary one you can't get along with or be friends with and so forth. They are a person which requires more psychological energy to maintain a relationship with than someone who doesn't hit your super-ego functions.
My reasoning is that when a person's ego consists of the functions in your super-ego, essentially what is occurring is their focus is on matters which are less important for you. Their focus is likely to generate a world outlook ([ame=http://en.wikipedia.org/wiki/World_view]World view - Wikipedia, the free encyclopedia[/ame]) which is not as immediate to you, and vice versa. This is the source of the conflict.
This doesn't however mean that it's completely impossible to get along with your conflictor, what it means is the following. In order to get along with a person who has an ego which is your super-ego... you must somehow convert your world outlook to one which fits better to theirs... this requires translating your ego functions to super-ego functions, which takes more effort than simply immediately receiving information which touches on your ego functions. Because of this... in order to "mesh" well with this individual, a lot of effort of psychological energy is required... in order to convert your world outlook to theirs, its like a change of basis (lin alg concept).
Also it's important to notice while the information elements tell us what information specific types focus on... it does not tell us about that information... i.e. personal experience. Therefore there is natural variation in certain people. If enough time is spent with an individual conflictor, it is possible to develop an understanding of that person to actually get a grasp on their world view and make sense of it in terms of your ego. This process however requires more of an energy investment than say a like quadra-mate or a dual. Also if you loose contact with a conflictor ally/friend, its likely your present ego-based model of their world view will become disharmonious with the changes they have undergone in that time and energy will have to be invested once again.
So essentially to sum up, the conflictor is not one who you must always be at conflict with... what is really means is the amount of psychological energy required to understand the other person's world outlook in your own terms. Duals require very little energy to understand, their world outlook actually functions as an inspiration for your ego. Identicals require no energy to understand, but once again this doesn't mean you will agree with them in terms of individual differences... its just that there perspective will be immediately recognizable as something familiar to you instead of foreign. The dual seems foreign, but they are a welcome foreigner who is constantly inspiring you. The conflictor is a foreigner who has a perspective that drains you psychologically due to the large amount of energy investment to interact with them, but this energy isn't wasted, it just goes into strengthening your super-ego... which is a naturally stressful situation. In fact I'd argue occasionally time spent interacting with conflictors helps make you stronger, by challenging you to use your ego to strengthen your super-ego... its like expending energy to work out... except its psychological in nature... enough time with a conflictor will exhaust and deplete you, just like working out too hard will.
