:::The blog link was in the Wikipedia:External links section; thus the verifiability policy is not particularly relevant.  From the external links policy, "Sites with other meaningful, relevant content that is not suitable for inclusion in an article, such as textbooks or reviews."  Also, "Linking to copyrighted works is usually not a problem". 
 :::From what I've read, the Huaorani were one of the most violent people groups on earth.  Life expectancy below 30 due to inter-clan revenge killings, and killings of anyone entering their territory.  Am I wrong? That to me is "violent".  Remember that that is the lead of the article and thus everything must be summarized; soon I'm going to add a paragraph explicitly sourced that talks about their history. 
 :::To me, "proselytise" has a negative connotation.  I don't really see the problem with "hope to present Christianity"—it's not like the Huaorani were being force-fed the stuff; the foreigners had a specific mission and goal but we're not talking about Spanish invaders killing the Indians if they don't convert. 
 :::It's bad formatting to describe a reference in the references section (it is never done in FAs, for example); I eliminated the text for a reason.  I thought the comment was aimed at me, and noting it, I deleted the text.  Once texts are included that are anti-missionary and are cited in the article text, it will be obvious which sources are anti-missionary (Thy Will Be Done, Fishers of Men or Founders of Empire, etc.), and which aren't. 
 :::I was hoping to continue with the narrative, but this Friday probably I'll start working on an Aftermath section, including a discussion of what different anthropologists think about all this.
