According to Wikipedia, the author of the article was the only American media correspondent that was placed full time in Haiti after the earthquake in 2010. He also published a book, his only book, of how the international help has left Haiti in worse shape.
Given his background, it doesn´t surprise me he´s vehemently pro-Haitian and anti-Dominican. Through the years I learned to research the authors of any article about DR-HT issues before reading the articles, because those that are against the DR use the same arguments -and the same lies and half truths- over and over again. I simply don´t waste my time reading what they write if I suspect they are not going to be balanced, at the very least. You read one one-sided DR-HT article where the DR is shredded to pieces and you basically read them all.
Needless to say that on which of the two countries a person is ´introduced´ to the island usually affects their biases when they have one. For the longest time I noticed that many foreigners that get acquainted* first with Haiti arrive on the Dominican scene with a very obvious pro-Haitian view of things. In a way it is expected, but sometimes I wonder what exactly are the Haitians telling these people about the DR. Some of them arrive with a sort of anger towards the DR. Some, after years of getting to know the DR, revise their original anti-Dominican opinions but they never fully give up their pro-Haitian stance. They simply get rid of the anger once they get a hold of a more complete picture of the situation and the history.
