It's strange, though, because I typically seem to get along with IxFJs swimmingly even though they have Fe/Ti. My INFP cousins are more likely to annoy me. It makes very little sense in terms of functions or letters.
But anyway...you can say that you have this or that in common with any type...all NFs are NF...NTJs and NFJs share Ni....IxFJs share Fe auxillary....INFJs and ISTPs both have Ti/Fe...you get the picture.
Bah.. I sound like I'm trying to enforce a direction in the discussion in this very post (Not that I have the power to do that). Just a thought, that's all. I'm not upset or anything. I just see something going wrong here if we project our conceptions of functions on to completely different types. It could apply to even Te. Like Kalach said: "Poor downtrodden Te" I'm sure he has to take crap for his Te because of.. someone's ESTJ dad or something.
Yeah a lot of people call Te the asshole function, so it can be downtrodden in that sense. Personally, I think ENTPs are assholes, too. Really any type can be an asshole, including my fellow ENFPs (then again, we have tert Te...)
