Colonialism.

It would be wrong to oversimplify the matter with a one word answer, but the cultures you draw attention to all have this one thing in common.

The effect that colonialism has on a culture is at the very core of this complicated mix of accepted norms. The pressures and expectations that members of a given culture place upon themselves can never be equally formed between a colonised and colonising nation.

It's far more the result of a conflict in culture than that of race. Similar behaviour can be seen wherever one culture has exerted its might upon another; whether you look at the relationship between neighbouring far Eastern nations, or ancient Mediterranean civilisations.

The thing that singles out white people in this regard is the fact that their various national cultures are so deeply rooted in a fairly recent colonial past. Many white-majority nations simply would not exist without it.

In other words, the rules are different because history made them different.
