In the West, we use “identity” language. This kind of language is a belief of modernity. Most don’t communicate it as a belief, but rather use it as a self-evident truth (again the assumptions there of our modern and supposedly enlightened era).
For example, the idea that one’s sexual preference is synonymous with one’s identity is a belief. It is an idea we believe to be true, and in the history of ideas, it is a rather recent one.
Identity language gets lots of play and lots of traction because we are modern folk with many modern assumptions.
