In their own words: "Cultural appropriation is a concept dealing with the adoption of the elements of a minority culture by members of the dominant culture. It is distinguished from equal cultural exchange due to an imbalance of power, often as a byproduct of colonialism and oppression" here
White culture is dominant as the USA is a majority white nation. (((White))) culture is dominant in media. Even if the demographic scales were to tip, there would be a long stretch of time where white people would be a huge minority of 49-ish%. Black, Hispanic, and Native American cultures are minorities far smaller than that. They are definitely not the dominant culture outside of their own decaying slums.
If any group of brown people want to become the majority culture of the US at a rate faster than they can import or reproduce themselves, they'll have to allow wipepo to adopt aspects of their culture. Except they can't see "cultural appropriation" without throwing a raging bitchfit about it. By refusing to allow others to appropriate the most unique or interesting aspects of their culture, these idiots have ruled out the possibility of becoming the majority culture.
They still need to go home, of course. It's just amusing to ponder how they are their own enemy here.
