give an example what a certain group would think is right, or what others would think is wrong

Sure, here's an example related to cultural differences:

In some Eastern cultures, such as in Japan and Korea, it's considered respectful to bow when greeting someone. This is seen as a sign of respect and acknowledgment. However, in Western cultures like in the United States or Europe, bowing is not a common practice and could be seen as unusual or even inappropriate in certain contexts.

So, for a group of people from Japan or Korea, bowing is the right way to greet someone. But for a group of people from the United States or Europe, this might seem wrong or out of place.

This example shows how cultural norms and values can influence what is considered "right" or "wrong" in different societies.
