Well that was... easy?
Anyway, it's interesting... is it the unconscious Ti that conflicts with Te or is it simple fact of directly differing priorities in Te and Fe? If Te in one person and Fe in another are both relatively conscious, could the people in question, all other things being equal, compromise?
Well unless someone actually says something about what Te and Fe really are, as opposed to what their products are, then that question can't be answered. But it's interesting that Fe seems to rely on Ti for some unconscious foundation as Te relies on Fi. Neither Je is supposed to be considered broken as a result. One assumes that where they are conscious, they are capable. But if it's true that there's this hidden Ji element to all conscious Je, then Te and Fe have built in rejections of each other, unrelated to content, directly related to form.
And if conscious Fi has a hidden Te structure, then Fi has a built in rejection of Fe methodology. Fe is recognised (unconsciously) as emotionally-driven stipulation about the environment when what stipulation about the environment is supposed tor reveal is its impersonal organisation, and any other attachment to the environment is and must be projection that blinds people to the real nature of things. Or, worse, it's fakery.
