Messy buns aren't only for wiry hair types. They never have been.

Hairstyles cannot and do not belong to a subculture. They belong to the culture at large and to any individual who wants to wear them. That's the nature of self expression and a participatory culture.

The problem with many afro harpies is that they grew up not knowing many people outside their genetic group. So they assign appropriation accusations to people who have their own cultural and historical expression. Willful ignorance really.
