I'm honing in on this bit: "they hold their values both inside and out".
I don't see E9 as being especially value driven, their MBTI type would have more influence on that, and as an ENTP; the type that doesn't hold and stick to strong morals for the most part, the influence is strong. Not that we're amoral it's just that we see everything in grey-scale when it comes to morals, there is always more information that can be brought to the table which can change the outcome so nothing is held to strongly.
So from an ENTP E9 perspective I do not hold my values both inside and out. I do have ease of access to Fe so outside values do play a part but personal internal values are more of a Fi thing.
I also wouldn't say that an E9 is ready to take a stand, everyone has their boundaries that once crossed means fight but the fight/flight response has E9s firmly in the 'withdraw' first category, figuratively speaking. We withdraw from problems, withdraw away from reality, we may not withdraw from a physical confrontation but we would first attempt to appease the situation verbally, we're peacekeepers when we can be.
If the definition of wimpy is to be "weak, cowardly, or ineffectual person" then nothing about an E9 has them placed either way, you could consider avoiding issues weak, you could consider avoiding conflict cowardly and you could consider not facing reality ineffectual, but they're not necessarily as the view is subjective.
The thing to keep in mind is E9 is in the anger triad, we are most out of touch with anger but it tends to go one of two ways when activated, rage or suppression. An E9 on rage would not be pleasant, or deemed wimpy I expect.
enneagram is all about values.
in fact, thats exactly what it represents, your values.
9 values peace and they are ready to defend what they value.
a mindless savage person attacks someone defenseless, and in this specific case you know its wrong, if there are no laws against killing the attacker, would you?
considering it would be effortless for you to do so, you are carrying a machete or something coincidentally in this lawless world.
no?
you could be the next target, too bad you didnt proceed into an action.
(Ti moral, while Fi might had done it even if it wasnt possible for them to be the next victim or if they didnt consider that possibility.)
just cause ti users have less values or they might be blurred doesnt mean you necessarily hold them less firmly.
fi generates values, but it _doesnt_ carry them out on anyone but _themselves_ by itself.
and with aid of Fe, i dont see why Ti couldnt generate them, besides Fe is more action oriented with their values than Fi. thus more likely for Fe's to act upon them, while Fi is rather working in the background.
just cause your values are selfish doesnt mean you dont have them.
you just arent well developed enough to include others in, which isnt suprising since maturity rarely is a thing NT's care about.
"there is always more information that can be brought to the table which can change the outcome so nothing is held to strongly."
that is true, and i value it to the extend nothing in morals is predetermined, only my own setting are and even they evolve constantly as i gain more self understanding.
"I do have ease of access to Fe so outside values do play a part but personal internal values are more of a Fi thing."
Ti can play the same role as Fi, you just valuate the internal side without feelings, by using thinking which can be developed and occasionally you will have to think about what you really want from life, in which case primitive Fi may come into play, unless your goal is 100% achievable without its aid as you anyways wont need it for anything else than to define what youre able to enjoy and that data is then for the rest of your life accessible without use of Fi, unless you want to edit your preferences. (aka not going in the mainstream. which is usual for healthy Ji before Je users.)
and you anyways use Fi, even ixtp's do.
its what dictates your set of preferences for leisure activities mostly, on Ti user types. you know those precious times when your more than just interested at something fascinating, when it goes beyond intellectual benefit.
for example, Se/Fe loops often enjoy watching others in pain, but i dont see this enjoyment coming empathy. but rather a primitive way of expressing Fi.
and this stereotype of Fi being moral function is just so wrong, as it has much more than mere values in it.
the role of Ji, both of them is pretty much to find a personal agenda for whatever actions whether inside or outside head you are to take.
the F element just means review in moral standards and T makes the standards based on effectiveness, and e/i is for the PoV and direction of use.
and by messing with the P/J E/I axis of mbti types, you can change the order of said processes and by messing with N/S + T/F you can mash whatever you require in the sense of criteria of what is significant.
we shouldnt try to simplify these things, they are all related and something which requires another cant be described as a whole alone.
same thing as if you slice car into half, it hardly transports you anywhere.
i guess these simplfying standards are set upon by the sensor domination.. which is rather destructive knowledgewise.
actionwise, ennea 9s do hold their values both ways. for the internal peace your ready for outside actions, to have the internal freedom. you are ready for self defence, while i would take the beating and were laws not stopping me, remove the problem permanently from this realm by later planned actions.
or in that case, i would prefer to remove the problem permanently before it becomes a problem in case there is no other ways, which often is the case for alcoholics wiith forever 7 year old violentic personality.
