Fi-Te do have a direct access to anger, imo. Fe-Ti would have to wrap it into more general acceptable forms of anger. That said, once developed properly, the Fe-Ti anger would be more effective because it has been molded in a way that it reaches the intended audience. Fi-Te would seem more like blurting out in that scenario like a skirmish and Fe-Ti would be more like an advanced and developed missile that can zero in on the target. If one was to imagine the whole thing even further, an Fi-Te would sublimate her anger into a creative expression while I don't know what an Fe-Ti would do. I have a really tough time understanding what Fe-Ti is like. They seem to be made of some other brain material altogether.
