>If I, a white man living in upstate NY, were to don Haudenosaunee ritual gear and record myself performing a traditional dance of theirs, that would be cultural appropriation.
No it wouldn't. It wouldn't be because cultural appropriation doesn't exist. Culture is not a zero sum game. You doing that takes away nothing from the originating culture.
>It refers to a dominant culture taking the trappings of a colonized or otherwise marginalized culture and using them for entertainment, for clout, or otherwise for our own purposes.
Ah yes, White original sin and The Protocols of the Elders of Zion-tier rhetoric about the international White conspiracy. Conspiracy theories about some "dominance" and hierarchy of cultures on some fabricated scale is what the Nazis used to justify cleansing Europe of the Jews.
>On the other hand, if I were to travel to Japan, stay at a ryokan (traditional Japanese inn), and wear the simple kimono they provide for guests, or go to a kimono rental shop and rent a kimono from them for the day, that would be cultural appreciation, because that is something that the Japanese offer openly as a way for foreigners to connect with and understand their culture.
Japanese offer openly people to wear kimonos anywhere. It's often a gift given so others can wear them outside of Japan. You can appreciate culture anywhere.
>In general, cooking and eating food of another culture in your own home cannot be cultural appropriation. (The only exception I can think of offhand is if the food is part of a closed religious practice of some sort.) Similarly with music—it's very unlikely to be cultural appropriation unless the music is part of a religious practice or being used disrespectfully. Hairstyles and clothing require a bit more nuance and can depend on the situation.
Not in general, in totality: none of the aforementioned things are "cultural appropriation". The concept is an illusion.
