The "genocide of Aboriginal inhabitants" was mostly the work of disease. When the Spanish arrived in the new world, they brought diseases that the natives never encountered. this resulted in roughly 70% of the natives dying in the 50 years after Columbus. This happened in Cuba as well. I love studying the Taino and Ciboney etc., always hoping to establish a link to myself. Alas, they were completely wiped out to disease and over work (their small bodies were not able to withstand the strain of slavery). The only remnants of their existence survive in the DNA of Cubans.
But to call what happened in the US "Genocide" is to distort the fact that the vast majority died by something other than intentional murder. Again, you are entitled to your own opinion. But you are not entitled to your own facts. So we can praise the native Cubans for our cigar habits. And for the words they left in our language: Barbecue, Hurricane, Tobacco, Cuba, Hammock, Papaya, Yucca, iguana and others...
