I've noticed that there aren't a whole lot of people who regularly interact with you in this forum and personally I find that unfair and rather sad. I don't know why that is but I suspect that most forumites shy from interacting with because they fear your reactions (?). I think they often forget that due to your condition (Autism, C-PTSD etc..), some triggers can make you feel overwhelmed by your emotions and as we all know emotions (especially negative) tend to linger longer in autistic persons and thus these emotions keep triggering the compulsion to discharge them in a cathartic way. That said, regardless of the cause, this is obviously an involuntary phenomenon that can cause relational issues and a lot of psychological pain for both the subject and his or her entourage.
Now, to most socionics aficionados, it would be almost inconceivable the person who find themselves in the aforementioned could identify as Fi lead, more so as an EII. Indeed, people would think that to not being able or wanting to build and maintain good relationships with everyone would be very untypical and somehow in contradiction with the essence of EII. But when they know about your condition, they should empathize a little more and be more tolerant.
That said,
I keep in mind that you have autism so typing you is a rather tricky endeavor regardless. You see, I suspect that the mental Track in the case of autism works differently. Indeed an autistic person is by definition self-centred, living almost exclusively in his or her inner world. Therefore the usage of indicators provided by the SSS typing methodology and which allow us to determine the location of the function might not work as efficiently as they should. It seems that with autism one specificity of the Mental track is altered namely the social/public orientation.
Now, autism is mostly related to social communication and interaction (Fi and Fe info aspects). So If let's say an IEI is autistic, his or her Ethical IE which are supposed to be strong would be de facto under-developed and thus might induce communication and relational issues. In addition the T functions should be a bit more developed and seem stronger (accentuated) that they should according to that type.
I suspect that there is a composentory phenomenon happening in the case of autism which strengthens the psychal action of the mobilizing function (Ti in the case of IEI) without affecting neither the order of blocking (accepting / producing) nor the dimensionality of the function. I also suspect that this phenomenon can accentuate the need for the subject to be appreciated in his or her mobilizing function domain.
That said, it would be logical to assume that an autistic IEI would resemble an ILI in terms of behavior and interpersonal relations. So I suspect that your SSS type might be more IEI-ish then EII-ish But I haven't tried to type you properly, like I said your case is quite special. Grigori Perelman would be a good contrasting example of an ILI with autism.
Now, about your avatar !
Can you tell me what emotions and message are expressed in the face and overall attitude of that character ?
