I'm not one of those people always who opposes Snopes or Wikipedia. When they are right, they are right. However, when they are wrong, they are wrong; and Snopes is wrong with this one. In an article titled "Did Christopher Columbus Seize, Sell, and Export Sex Slaves?" Snopes claims it is true. Unfortunately for them, ALL the claims of the article are false. They did a poor job investigating: They used Howard Zinn as a "source," even though he was not a primary historical source, but just a revisionist from the 20th-21st century. 

They also used  "A Brief Account of the Destruction of the Indies" by Bartolome de las Casas, even though the book is about events that happened AFTER Columbus was out of office. Contrary to what Snopes claims, Las Casas was not one of Columbus' crew members and he always admired Columbus describing him as a hero, a brilliant man, and as a good Christian.
