people accuse others of cultural appropriation way too much
when i see someone online or wtv doing something belonging to black-american culture, such as dreads, many people come to attack them, calling them racist and a cultural appropriator. i personally think that it really isn't cultural appropriation if they know where its from. to me, it's on the same level as a non-japanese drinking matcha, or a non-indian person eating butter chicken and naan. cultural sharing is common because of globalisation and inevitably, people are going to consume and adopt things from other cultures that they find interesting or they get pleasure from.
similarly, people saying people who aren't black americans shouldn't make hip hop or jazz is also silly, because again, when these are shared with a wide global audience, people are gonna be inspired.
i've only really seen this in black americans, not even other black people. like, one of my indian friends wore a sudanese dress, and my sudanese friends didn't mind at all, called her pretty, etc.
this doesn't mean that cultural appropriation doesn't exist obviously. one example i can think of off the top of my head is people calling duppattas 'scandanavian scarves', like thats very clearly wrong.
