Answer:
By not imposing the our cultural standard toward them.
Step-by-step explanation:
When judging the personalities of people from another country, people have the tendency to use their own cultural standard as a measurement to judge their behavior. If they see a certain action/behavior as "bad" in their home country, they tend to assume that it will be considered as such in another country.
In sociology, we often refer to this as Ethnocentrism.
We need to realize that the difference in culture could influence the perception of what's 'right' and what's 'wrong'. This will most likely influence the way people usually behave. So, rather categorizing the behavior/personalities of another country as 'Weird' we should remind ourselves about that cultural difference.
