Balkissoon dismisses what she learned in The Orenda now that JB's heritage is questioned, but didn't before that...
Fiction does not claim to be factual nonfiction.
Biases exist in fiction and nonfiction.
No one knows whose recounts of life and events was most factual and objective - the written Jesuit accounts of the time or the oral stories of the FNs?
Opinions like that of this column smack of resentment amongst SJWs who want to write their own revisionist history and tear down all of our accepted history no matter how scholarly it is.  It is also wrapped up in the notion that one cannot write scholarly accounts of another culture or race because they label that 'appropriation' which is nonsense.
The Orenda is fiction.  Read it and enjoy it, and take from it what you choose, and then read more books on the subject.  Don't condemn the author and his works.
How much of this condemnation coming  from the angry authouritarian left  is because Boyden rightly defended Steven Galloway?
