Nor does preventing whites from wearing locks or practising yoga challenge racism in any meaningful way.
The bane of cultural appropriation
Al Jazeera English

Disagree. First off, it’s not about preventing. There aren’t any culture police forces to stop people from doing what they want to. It’s about groups coming together to put those who appropriate on notice. Because they should feel shame if they practice a skewed, inauthentic, or disrespectful aspect of a culture without recognizing the importance of what they are doing and how their appropriation negatively affects and further marginalize those peoples. Because appropriation mostly happens from one dominant culture or race taking from a less prominent/powerful one. It’s almost always in that order.

Second, saying that challenging cultural appropriation does not affect the fight against racism in any way is plain wrong. Challenging false narratives is exactly how you wage war against racism.
