Here come the observations from someone who is Se-seeking:
I've usually seen Se PoLR people as being "frail" somehow. Not necessarily always physically, strictly speaking (though that too), but it is like their body language expresses a certain frailty. As if one blow could easily knock them out. It is like their being is permeable, not resistant enough. Se-seeking/activating people may also possess a similar kind of frailty, but it is less pronounced. I believe this boils down to them being actually "open" to Se, whereas Se PoLR is not. And I can see it somehow, as someone who is unconsciously looking for Se.
In comparison, my ESI E9 friend is pretty small and an outsider may describe her body stature itself as "frail". However, she still looks physically resistant and "well-grounded", which I admire. It makes me feel good and safe. This has applied to all other ESI people I've known. Many of them are rather thin people (not always, of course), but they still have seemed so much more physically "resistant" than any Se PoLR people I've known.
I believe this is what Se PoLR basically boils down to. It is partly about the relationship your body has to the external world, how it moves there, how resistant or open it is to outside invasive stimuli, etc. Given it is Se
PoLR, that particular relationship is rather negative. Whereas Se-seeking people will have an "open" attitude towards it, somehow, which expresses itself in a "positive" way. So much so, them being weak at Se is sometimes not even noticeable.
Finally, Se PoLR will tend to appear to be (physically) "weak" to Se ego types and some Se-seeking types. Simply because those types value strong Se, strongly. :p
But hey, there is no use in worrying about that. It is like worrying about not being able to appease your Conflictor. You cannot please everyone. For example, Ni PoLR people often negatively comment on my "inactivity" whenever I am "going deep" in my mind, introspecting while not moving around much. Seeing me engage in that sort of "dream-like"/meditative state makes them uncomfortable.
Personally, I don't find Se PoLR people to be weak in their character categorically. As others have mentioned before me, Ti and Fi doms "compensate" physical weakness with ideological strength.
Having said that, I do get the sense Se PoLR people are not strong (enough for me)
physically. But that comes from someone who has weak Se themselves and is looking for strong Se in others.
P.S: @
chips and underwear , rather don't define yourself by your weakness. You don't give your strengths any justice by doing so. Focus on your strengths, and shine.
