Cultural relativism is the belief that all human behavior is the product of innate cultural values.
In practice, it means that all beliefs are justified and all actions are in the best interests of the group.
The aim is to make people accept that others are, in fact, different and that they have rights.
The movement has been gaining momentum over the past few decades, with some organisations even saying they are an extension of the left-wing left.
It’s a belief in human superiority, with the idea that the differences between people are because they have different brains and cultures.
Critics argue that this leads to stereotyping, prejudice and bigotry.
But many of the same people who champion this view also believe that the idea of cultural relativism makes people racist, sexist and bigoted.
