Blackbirding in Polynesia seems to be a new twist in history to make it seem as though in Polynesia there was a legitimate slave trade. According to research, in Polynesia it was not even close to being a "Slave Trade" but very few accounts of "Kidnapping" which seem to have been blown up to belittle the people in the region. The islands mentioned where the kidnappings took place are places where population is low. However, there are numerous accounts in Polynesia where the reversal took place and Maori enslaved European traders. In fact every man who was captured alive by Maori standard, was given the duty of slave to the Iwi or man whom captured them in War.
The term though "Blackbirding", seems to be a very racial term, and it's wondered if this was targeted only to the darker skinned community. Melanesia may be settled by a darker toned civilization but they are still Asian. Southern India has such cultures and they too are still Asian. In fact they are an important part historically to all the many Indian Cultures
