Anyone can and will wear whatever they want and you have absolutely ZERO power to stop them. There’s no law against it. Anyone can wear a native American head-dress, anyone can wear Japanese yukata, anyone can get whatever tattoos, speak whatever languages, partake in whatever activities, people...
Why do so many white people care so little for the feelings of the people they are appropriating? Like you want to wear a warbonnet but don’t give a fuck about the Native tribes that still practice the use of them. In your mind it is all about you and your wants.
