PORT-AU-PRINCE -- When Jamaican officials snubbed a group of young Haitian soccer players who visited two years ago on the heels of a deadly cholera outbreak in their quake-torn homeland, a revolted Marguerite Rigaud immediately went into action. In a matter of days, the Pétionville restaurateur had thousands of Haitians marching through the streets of Port-au-Prince protesting the boys’ mistreatment by a fellow Caribbean nation. “I couldn’t believe that another black nation would do this to a sister nation. I found it revolting,” Rigaud said.
