Truth is exclusive. Culture is not created in a vacuum. All cultures reach for a transcendent reality to anchor themselves in, hence the root word Colere or Cultura, denoting growth and cultivation (a bacteria culture) or when applied to human society meaning "the customary beliefs, social forms, and material traits of a racial, religious, or social group" (taken from https://www.merriam-webster.com/dictionary/culture). Cultures are either objectively bad or objectively good (Christian culture being the only good).
