Take A-rods genetic sample. It will show pure Dominican traits since he was "made" by a Dominican father and Dominican mother. That guy probably has more genetic mixture than most Americans have, thanks to the mixing in the DR.
The reason (in my opinion) why Dominicans are not very fond of A-rod ever since he decided to "privar en ser gringo" as they say, is because he is still considered a Dominican.
Why?
His flesh and bones are from Quisqueya 100%. Had his mother wait the full 9 months in the DR before heading to Florida when she was pregnant, A Rod would have been born, looking the same but in the DR. As such, he's a "genetic" Dominican.
Most Dominicans expect "genetic" Dominicans to identify at least a bit with the island nation that eventually made it possible for him/her to come into existence. After all, the actions of Juan Pablo Duarte back in the 1800s had an indirect effect into everything the DR has fallen into, even the minute things like the pregnancy of A Rod's mother to give birth to him. If the DR was never created, A Rod's parents probably would have never met or not even be born, etc. As such, some pride for the island is expected.
Unfortunately, there are many "A Rod" types around. They were born elsewhere, though from Dominican "parts". They learn to live double lives (one as Americans and the other as Dominican expatriate) and due to their lack of interest in Dominican culture, its history, its development, add to that the possibility that he equates the DR with poverty and not knowing nothing about the DR will make A Rod or anybody under those circumstances feel ashame.
He also looks at most Dominicans players, who are much darker in complexion than himself. In American baseball, Dominicans are perceived to be charcoal black, despite the truth being more varied. Becuase he was sorrounded by the US black/white mentality, he might not want to be assosiated with a country that is wrongly considered black. That could also be another possibility.
To tell you the truth, its quite evident that A Rod is a "proud" man, a little too proud and that pride could very well have lead him to pick the US over the DR.
Now, Sammy and Pedro and other players help around the DR with charity and certain economic development incentives they have tried to create in their communities (Sammy's 40/40 Plaza is a good example in San Pedro). The question now is, A Rod with all his millions and publicity, which charity has he helped out for those Dominicans who were not fortunate to have their mothers move to Miami while they were still in the placenta?
These are things Dominicans have been watching for sometime, but conveniently rejected, until A. Rod made it clear that he denies his roots. He could very easily have said "I'm American of Dominican decent", but he didn't and when commentators and reporters refer to him as American or don't include him in the list of "Dominican players", he does nothing to add that extra fact that is so fundamental to his existence.
A Rod is American of Dominican decent. In my opinion, he should always mention that, not just American.
Its like a mulatto saying he's only white or black when in fact he's both!
A Rod should be more like Felix Sanchez. A Rod should embrace the American culture as much as Felix Sanchez embraces the Dominican culture, but A Rod needs to learn to never reject or omit an important part of who he is.
Felix Sanchez loves the DR and its quite clear bringing Olympic Gold to this country, but he is very much aware of his American roots and despite he being obssessed with the DR, he never denies his American roots or omits it.
A Rod in the other sense, is a disgrace compared to Felix Sanchez.
A man that can't be proud of his roots, is a man that can't be proud of himself. Afterall, one's roots are the cause of one's self and although people have a choice as to what they want to do in life, the one thing people can't choose is who they are and their own roots.
People don't choose in what country they should be born in or to what parents, but people must give some credit to everything that they are made up of equally, not just one side.
That is my opinion on this.
