Why is embracing the beauty of a culture offensive? I mean, people have forgotten your culture and these celebrities are embracing it in their art.....

The war bonnet is offensive because it's usually used to generalize "all Indians" rather than the specific Native American clans that wore it. It is also HIGHLY symbolic to some contemporary Native American clans, so it is like a slap in the face when people wear it for "fashion" or as a costume.

Are you wearing it in full and respecting/learning the traditions of the people who are famed for it? It's as worse as wearing a burqa with a bikini.

It's not respectful.

No different from Azealia Banks wearing Indian beads on her forehead

And Madonna is appropriating black culture with those golden teeth in your avatar, so.

Why do you keep making thread topics on subjects that you'll never understand at your age anyway?

What? NO.
