I meant that the positions 1,2,3,4 are typical for large and complex societies (not only Western ones),and 5,6 for small and primitive societies. The main difference is that in a primitive society, your tribe interacts with the strangers often. In a large society, unless you live on the border, the vast majority of your interactions is with your neighbors. Your opinions about strangers are mostly for signalling for your neighbors, because you interact with strangers very rarely.
My assumption is that people are usually antagonistic to their competitors. This is why in a small society I expect more overt hostility to strangers.
A large society usually has some rules to supress hostility, but more importantly, most of the remaining hostility is targeted towards your neighbors belonging to the opposing faction. Thus less hostility towards strangers. Actually, your faction can use friendly attitudes towards strangers as their attire. It does not actually have to be sincere. (For example, as an anti-racist you are not required to have friends among people of other races. And having friends among people of other races does not make you an anti-racist; it will usually not be even accepted as an evidence. The only requirement of an anti-racist is that they must hate racists and support other anti-racists. And symetrically, the only requirement of a racist is to hate anti-racists and support other racists. The actual hate towards people of other races in a private life is not required. It's about belonging to a faction in the internal conflict; the actual strangers are mostly irrelevant. A person worshiping noble savages is not expected to adopt their lifestyle. Only to worship them, and thus show superiority over the less enlightened neighbors who don't worship the same noble savages.) So the complex society can split along "anti-stranger" and "pro-stranger", or "strangers are the same" and "strangers are different" axes. Unless is has other, more important internal divisions, for example religious ones.
My position is that people are biologically very similar (1), but living in some culture often makes them accept the cultural norms, which can seem completely crazy to us (4 - with the exception that we should morally care about what they do to their own people; we just shouldn't naively expect that they will share our concerns). I do consider complex cultures mostly better than primitive ones (2), with one significant exception that a life in a primitive society, although shorter and more painful, is probably less frustrating (3 - in one specific aspect, which is rather low on my personal priority list).
I think that in Western societies, political correctness plays the role religion has in other societies. So I would expect other societies to be less concerned about strangers, and more concerned about whatever is the burning religious topic for them. So instead of using strangers as arguments for their political positions, they would use something else. But they may be mindkilled about strangers because of what their religion says about them.
I don't see what you mean by political correctness playing the role of religion.
WEIRD may be weirder than you think. We Aren't The World writes of psychological experiments on non-Westerners that give vastly disparate results from results that have been assumed to be hardwired, and the implications of this:
Henrich used a “game”—along the lines of the famous prisoner’s dilemma—to see whether isolated cultures shared with the West the same basic instinct for fairness. In doing so, Henrich expected to confirm one of the foundational assumptions underlying such experiments, and indeed underpinning the entire fields of economics and psychology: that humans all share the same cognitive machinery—the same evolved rational and psychological hardwiring. The test that Henrich introduced to the Machiguenga was called the ultimatum game.
...
To begin with, the offers from the first player were much lower. In addition, when on the receiving end of the game, the Machiguenga rarely refused even the lowest possible amount. “It just seemed ridiculous to the Machiguenga that you would reject an offer of free money,” says Henrich. “They just didn’t understand why anyone would sacrifice money to punish someone who had the good luck of getting to play the other role in the game.”
...
At the heart of most of that research was the implicit assumption that the results revealed evolved psychological traits common to all humans, never mind that the test subjects were nearly always from the industrialized West.
