There is no such thing as a "typical Native American man in the street".
There are hundreds of different tribes, each with their own spiritual and cultural beliefs.

This is one of the many reasons why native American fancy dress costumes are so offensive to native people, because they often mix and match elements of different cultures together in one costume.
The situation is further complicated by the fact that countless non-native people claim to be native chiefs, medicine men and women and steal and pervert elements of sacred ceremonies for their own financial gain.
Often, when a native American voice is needed for news reports journalists fail to ask genuine native people for their opinions and instead ask fake native people.
There are hundred of fake tribes, many consisting of scammers and racists.
The fact is that many times struggle with poverty, the emotional impact of genocide and multi-generationl trauma.
If people really genuinely wish native people well and would like to support them in recovering from the consequences of actual and cultural genocide then not dressing up or dressing your children up in "native American" themed fancy dress is just one small step.
The second thing to do it to start to educate yourself about the genocide of tribal and indigenous people all over the world and to fight against racism, oppression and cultural appropriation.
