The Dark Horse of Cultural Appropriation and Plagiarism?

How un-Christian (or un-Mithrian) 
of you Katy Perry?-)

"Plagiarism is the "wrongful appropriation" and "stealing and publication" of another author's "language, thoughts, ideas, or expressions" and the representation of them as one's own 

original work."

"Cultural appropriation, at times also phrased cultural misappropriation, is the adoption of elements of one culture by members of another culture.
This can be controversial when members of a dominant culture appropriate from disadvantaged minority cultures.
Cultural appropriation is considered harmful by some, and to be a violation of the originating, minority cultures, notably indigenous cultures and those living under colonial rule.
Often unavoidable when multiple cultures come together, cultural appropriation can include using another culture's religious and cultural traditions, fashion, symbols, language, and music.

According to critics of the practice, cultural appropriation differs from acculturation, assimilation, or cultural exchange in that this appropriation is a form of colonialism: cultural elements are copied from a minority culture by members of a dominant culture, and these elements are used outside of their original cultural context—sometimes even against the expressly stated wishes of members of the originating culture."

"Fireworks were originally invented in China.

One of the cultural practices for fireworks was to scare away
evil spirits.

Cultural events and festivities such as the Chinese New Year and the Mid-Autumn Moon Festival were and still are times when fireworks are guaranteed sights.

China is the largest manufacturer and exporter of fireworks in the world."

4th of July fireworks appropriately enough?-)

I'm with Benebell Wen and Jordan Peterson 
(or am I just appropriating their ideas on the subject?-) when it comes to "cultural appropriation" and I'm no fan of plagiarism, but good luck in this wide world in trying to figure out just who stole what from whom, or "appropriated" it.
