Or cultural participation. I would need way more context about both the cultural practice and the planning of this event to be able to have a clue whether this is cultural appropriation. Just looking at a picture of someone participating in another group’s cultural event is not enough.

Especially as a white person, it would be naive if I just started looking up pictures of people participating in cultures that I don’t know anything about and claiming that appropriation is happening. Context is important.

Edit: according to that article, this is literally an educational event intended to spread awareness. So I’m leaning towards this probably not being appropriation until I see a good reason to think otherwise.
