Here is mine
There are too many generalizations here. I believe the whole thing is a class and political problem.
Dominicans are mostly pro-Fidel Castro. Therefore they hate Gusanos, not Cubans. Dominicans and real Cubans(Those in the island) have a respect and friendship towards one another. Jealousies between peoples are normal. We may have an envy for Cuban amateur sports figures, but Cubans look up to our major league players and see a challenge. They hate the freedom we have. We wish we had their health and education.
Gusanos are hated by the entire world, not just us. The American people wish they just go away, but have to live with them.
Puerto Rico is a different story. There are the Puerto Rican blue bloods and the rest. The blue bloods not only hate Dominicans, they hate everybody who is not in their circle. Our Dominican blue bloods are simpler people.Obviously, Dominicans in DR are not hated. What is hated are DominicanYorks, DominicanRicans, or Dominican inmigrants, who are the scum of the Dominican people. Most Dominican inmigrants are low class, uneducated brutes. They are arrogant, ill-spoken and ignorant. Most are hard workers, and honest but they are still crap.
Even Dominicans here are not too fond of Dominicans abroad. We take their money(most poor families live off their income) but we still hate their guts. It takes the government doing publicity campaigns to be sure we welcome these boat and lechera people back with their greenbacks and gifts every Christmas. The worst crimininal element in DR is exported back to us. Most Dominicans abroad are society*s economic and social rejects, unless they are rich students or people looking for masters degrees and PHDs, or in serious business.
I love Puerto Ricans in general. Puerto Ricans are an important tourist factor in DR. They have the best music in the world, bar none. Their artists are the best in Latin America. Be it salsa, merengue, bolero, reggeton, rap, guajira, pop and even rock they do it all better than everybody. They are ready to take over bachata soon. I dislike their baseball players, but it is just the competition. They have the second finest, after us, pound for pound. They are the best dancers in the world. Their New York dancers have no equals anywhere. They just plain cool people. Puerto Ricans hate Dominican inmigrants, but when they visit DR they have a differnt view of us. They know we are pretty much alike. Except for Venezuelans, there is no other nationality as similar as we are as Puerto Ricans. When I lived in the U.S. nobody thought I was Dominican. They identified me as PR. Thats because Puerto Ricans in New York are mostly light skin and very modern in their looks. Dominicans look "atrasao".
As for the politics. We hate Puerto Rican dollar power. They hate our sovereignty and nation power. Other than that is just politics and inmigration.
