alright alright alright... I suppose there's no harm in providing a few reasons (as long as I don't get sucked into a debate).
First of all, yes... my typing methods are partially subjective (looking at shared quadra values and intertype relations and whatnot). I'm not interested in debating the validity of these or any other typing methods, but there are existing debates as such scattered about the forum if you're really interested in understanding my reasons.
Anyways, I'll start with discounting my former reasons for thinking that they weren't SLE and EIE.
For a long time I've thought of SLE's as one of the types that I didn't particularly get along with or think much of, but upon a little bit of reflection, I really don't know why. I've pretty always sort of superficially "clicked" with the SLE's I've met irl. The way I get along with SLE acquaintances is not all that different from the way I get along with IEE acquaintances, which makes sense. They're not people who I think "wow, I would really like to get to know him/her better", but there is an ease in communication and I seem to "get" them the way that IEE's seem to "get" me.
I have come to believe that my past understanding of Si PoLR's was also flawed. I definitely think it's possible for people with a Si PoLR to consistently train their body or enjoy regular physical exercise. They may do it with a different mindset than types with strong Si, but they are capable of doing it just the same. To give an example, I think Arnold Schwarzenegger is LIE, based on what I know of him (which admittedly isn't an enormous amount). The bottom line is that I was using a Si PoLR to explain some of my character flaws (instead of just doing what I needed to do to fix them). This led to a grossly inaccurate understanding of the capabilities of Si PoLR types.
As for the reasons that I think that FDG is not SLE (or SEE, for that matter), they have mostly to do with Fe and Ti, and to a lesser extent Fi. Basically, I don't think he's SLE for the same reasons (related to Fe and Fi) that I don't think Ashton is SLE (see what I wrote about his type on the wiki consensus list if you're curious). Also, Ti dual seeking makes more sense for him than Ti PoLR or even Ti creative. Look at how he responds to (and greatly respects) Ti explanations, but also note the lack of Ti in his own posts. Ezra has readily shown more Ti than FDG has in the way he came here immediately looking to correlate typology systems (that is, to understand Socionics at least in part by figuring out how it fit into the existing framework of other typology systems he already understood). Also, he was not at all quick to discard/get past some of the early correlations and understandings he had built into his framework of understanding of Socionics.
One could argue that Ashton has built his own Ti system, but I think the difference is that Ashton's Ti system was built over a longer period of time and is much more comprehensive than Ezra's. It's more of a rational approach to Ti than an irrational/creative approach, you could say. I think the reason that FDG hasn't done the same thing Ashton has is that he simply isn't willing to put that kind of time or attention into Socionics. FDG appears to be a more healthy and balanced person, and it sounds like he has some very time-consuming interests outside of this community.
The thing about FDG that doesn't fit into the EIE typing is the appearance of a laid back outlook on life. The fact that he identifies with +++ and enneagram 7 does seem more EP-ish than EJ-ish. His signature strengths also seem more SEE (or at least EP) than not. I still think EIE makes the most sense for him overall, though.
As for Ezra being SLE, I don't have a huge case to make for it (or rather, I don't want to invest the time required to make a huge case for it), but I think most people already think he's SLE and there have been many cases made for this, so aside from what I already said about his Ti approach to typology theories, I'll just offer my subjective reasons. The reason I was thinking about it and changed my mind about my typing of him is because I had a SLE client yesterday and had talked at length with a SLE professional acquaintance relatively recently and the way they responded to me reminded me of the way Ezra responded to me. One aspect of this was that they seemed to appreciate the Ni way I explained things (rather similarly to how I appreciate the Fi way IEE's explain things, actually). This is part of the ease of communication that I described above.
So anyways, my intention in making this thread was not to convince anyone of anything, but rather to simply state that I have changed my opinion. This post offers some of my reasons, but as I said before I have no interest in or time to invest in debating or further explaining my reasons or either of their types.
