Why do Puerto ricans hate Dominicans?

There is no evidence that Puerto Ricans hate Dominicans. In fact, there is a long history of friendship and cooperation between the two countries. Many Dominicans have migrated to Puerto Rico over the years, and they have contributed to the island's culture and economy. There have been some instances of tension between the two countries in the past, but these have been largely resolved. Today, Puerto Ricans and Dominicans enjoy a strong and positive relationship.
