This is related to the slavery discussion, but Amarr/Caldari in general, and even Minmatar/Gallente.
The Brothers of Freedom event saw State authorities gun down sixty-five thousand protesters. It is likely that the Caldari see them more as 'traitors' than protesters. There's a Caldari storyline mission I believe, that mentions that the Caldari see those who migrate to the Federation to seek employment as traitors and scum of the earth.
The question I pose is; why would the average and loyal Caldari individual see anything wrong with the authorities gunning down 65k 'traitors'? An answer would come WITHOUT rationalizing it as a Western consumer. We would see stuff wrong with it because of natural/inalienable rights we have as Westerners, that people are allowed to protest against our government. But we rationalize that as Westerners. The Caldari are not Westerners; they are Caldari. They do not believe in democracy, individual inalienable rights etc.
But whenever I see someone RP a Caldari as per the "corporate dictatorship" description (right there in the character creation), they get alienated, just like slavers. I mean, Diana Kim is a caricature, but in the right direction IMO. Same with extreme Gallente who act all like cultural colonialists. That is equally within the PF's bounds because it says that the Gallente vary widely in their opinion, unlike the other races.
(BTW, I'm not saying the Fed don't oppress; they just don't get caught doing it. They'd rather knock off the ring leaders and call it a hovercar accident, whereas State would be like "Correct, we took care of all traitors")
It's just the general idea of RPing beyond our comfort zones, regardless of faction. The acceptable moral standard in the Summit and elsewhere is basically as per our RL/Internet moral standard. But EVE is not RL (stfu ccp), nor the Internet. Capsuleers must respect self-determination, individualism, several inalienable rights (that don't seem to have any source within the world), and so forth. Meanwhile, most of New Eden don't bother with doing so at all.
Perhaps it's just a facet of capsuleer culture. It all just seems like spineless UoC Gallenteans to me, heh. And ofc, playing a Gallente in-character, calling other characters "You all sound like Gallenteans to me" will be met with hostility...even if by all measures, everyone IS behaving Gallente-ish (that said, the Dove kind rather than the cultural imperialist kind).
Alternatively, at the end of the day, Summit RP is "light" RP, so playing proxies of ourselves with similar RL viewpoints is the order of the day. And there's nothing wrong with that; like I said, not everyone has the time/effort to go Full Srs with RP. But at the same time, I don't see why people who attempt to RP the faction as per the source material (and not by the Summit's Moral Consensus) should get shot down. I perfectly imagine, on numerous times, completely newb RPers who pick Caldari in the character generation reading them as "ruthless and cold", go into the Summit COMPLETELY unaware of the moral standards established. They then go to RP how they think Caldari would act according to the PF they've read so far, only to get torn to pieces because of how politically offensive they sound to us as players.
