Well, you certainly have done a wonderful job of appropriating English sanctimony and hypocrisy.  For one thing, you wrote this in English...which I didn't know what a traditional native language.  Appropriation number one.   

Look around you.  In your everyday life, (which is what culture is as people are living it), how much native customs do you live by?   Face it...other than the colour of your skin, I seriously doubt you live any more historically native than I do.

You adopt white culture with impunity....worse, treat white people as if we are all the same and don't have any culture regardless...and cry and moan when somebody takes license with Riel....a man who, as Metis, was half white.  But nope...that white heritage means nothing.  It's how YOU judge the interpretation of the native half that's important to you...as if Riel, or any person, can be split into his or her ancestral components.  

Many native cultures fought wars....who did your ancestors steal their land from?
