I still think that's wishful thinking in an effort to make the Caldari out to be the Mirror-Universe "Terran Empire" from Star Trek where Mister Spock is always plotting to kill Kirk.
Sorry, but I find the idea that Caldari are uncaring bastards by a rule to be ridiculous, just like I find the idea that Amarr are mustache twirling slaver-villains to be ridiculous.
EDIT: Also... Kinship does not equal Minmatar. Even the Amarr have a sense of kinship through their common religion, and Gallente a sense of kinship through more western concepts. The Caldari certainly can have a sense of kinship based on national and racial identity without being 'Minmatar'.
People seem to assume that I somehow hold the opposite view. As much as I am cautious when taking literally what the PF says about Minmatar and how they care so much for their enslaved kin, since I believe that most Minmatar, being human like anyone, have other things to care of than thinking to a kin they lost generations ago and living far far away, it is still PF and can be explained because their culture has always been completely based around the concept of kinship and tribes.
And I am no Star Trek fan so I know very little of that universe, so not really understanding the analogy, sadly
The concept you have to get your head around is 'coopertition'.
The idea that a society could manage to struggle even to the stage of tribes or bands without the ability to extend the concept of kinship beyond the immediate family is, frankly, laughable in sociological terms.
The Caldari are a faction that was founded in a struggle for existence. The idea that they could have succeeded as they have whilst acting in the way you suggest is just not feasible.
I do think that what the Caldari strongly care for is not their kin, it is their society, their culture, and the well being of the collective. I do not see what is "frankly laughable". You do not need to care for your kin when survival is involved. It can even become quite the contrary (not saying it is in the case of the Caldari though).
You only have to care for your community and what is harmful to it, but I would clearly expect the average individual being extremely cautious and protective even when dealing with his "kin". When resources are rare, you do not live in a happy world where everyone love their kin.
Yes, coopertition. They cooperated not out of love or care for their kin, but out of necessity. I would rather argue that it is your view, that is not really believable to me. vOv
Overall from experience since I started playing, I have noticed the Caldari and the Minmatar interpretation among players to shift slowly toward each other. It's not said as an attack or a YDIW (even if it does not really make me happy, whats the point to have Minmatar cyberpunks and Minmatar corporatists ?).
The Caldari are now seen very caring for their kin when the Minmatar are now also seen very caring for the collective, which I believe to be biased and quite false as well : the latter is a Caldari trait, the Minmatar do not care for the collective more than anyone considering their strong emphasis on freedom and individuality, they just do their duty to their tribe and kin when asked, and do whatever they like besides. I would argue that the Caldari feel directly threatened when their culture and society is threatened, when the Minmatar will feel threatened when it's their very blood.
