It's definitely cultural. I realized this sounded exactly like my forum behavior in the past (and of course forum societies are a reflection of a person's most obvious traits, even if other traits are obscured due to lack of ability to read tone, facial expression, and so forth on-line):
This culture of honour is also shared by people who live in inner cities (i.e. what people would call honor amongst thieves, we treat insiders with honor, and outsiders like crap)...and this may be something I also shared in common with my ESFJ ex who grew up in Las Vegas, and often frustrated me with what I saw as ridiculous references to his neighborhood, but that's all he had, in sharp contrast to me, who has a whole historical culture and extended family history to ramble on about. I was too young and immature at the time we were together to even acknowledge that I was culturally more privileged in some ways than he was, because I viewed him as being so informally well-educated since he had such an interesting cultural background, and also his mother was a real flesh and blood European, and his taste in art and film in particular reflected this sophistication, which he said separated him from his Las Vegas peers growing up.Once a culture of honour exists in a society, its members find it difficult to make the transition to a culture of law; this requires that people become willing to back down and refuse to immediately retaliate, and from the viewpoint of the culture of honour, this tends to appear to be an unwise act reflecting weakness.
If this is true, then I feel most comfortable or safest with men who share values of cultures of honor, since my ex believed in personal integrity and personal vengeance (in kind of a ridiculous extreme in his case, though) and gender roles...and even recently I dated someone from Virginia, and I already mentioned JTG's perception of personal vengeance of honor, and me later realizing that this may have had to do with traditional Japanese cultural influence on his morality.
It could also explain why I am attracted to people who will most likely cause drama for me and mine, since people who believe in personal vengeance tend to resist the law.
People from cultures of honor resist the law and see submitting to it as a sign of personal weakness.
This would be interpreted on MBTI forums as Fi, most likely.
