This is so Canadian - someone makes good, others tear him/her down.   Joseph Boyden is the best living Canadian writer today. 

Read his work, and then decide.  As to what his DNA says - who cares?  Unless his interpretation of what it means to be aboriginal in Canada is wrong (and I haven't heard anyone say that it is) then let's celebrate a writer who can open a window for us into an important part of Canadian culture.
