Emmet Till "Cultural appropriation" is a sloppily employed term. It's in a sense the very opposite of what is a real problem, cultural domination. When a minority culture appropriates from a majority culture, that's more likely to have negative effects on the former than the latter. And when the appropriation flows the other way, it seems odd to also call it bad for the minority culture unless there is some element of exploitation, perversion, or ridicule etc. involved. In which case, it would be cultural misappropriation. Like if a majority culture were to take a native culture's sacred ceremonial dance and make it into some kind of trivial fad that served to denigrate it, that would be misappropriation. White hip hop artists and rappers on the other hand are just culturally appropriating. And then you have everything in between including this painting, which unless someone can show me how it exploits, perverts or ridicules the tragedy it depicts, I don't see a problem with.
("How She Sent Him and How She Got Him Back" is a much better work of art though imo).
