Agreed. Ahem.
Regardless, I think I got a good feel of the real intent. Really interesting read... That guy was pretty entertaining. It certainly did hit on a lot of mysterious traits I've observed in the ENTP's in my life. The ENTPs I know certainly do come in a different "flavors", but regardless I've seen flashes of what this guy calls "Fi translated through Ti."
But really, I think it's Ti/Fe responsible for this, and can be seen in any Ti user (if the Ti user allows it

). Fe drives and motivates those feelings, and Ti expresses it. In other words, Ti users may be prone to rationalize internally a desire to have emotional control of our external world. To some, this may sound mild and detached, but it can be truly intense. I can definitely see why it may be mistaken for Fi.
Let me put it to you this way (though I'm a Ti-dom, not Ti-aux): I've experienced "love" through Fi and I've experienced love through Ti/Fe. As paradoxical as it sounds for most, love through Ti/Fe for a Ti user is a much more positive, beautiful thing. Fi love feels like despair. For a Ti-aux user, Fi may feel more like paranoia. But that's just a guess.
