There are no good or bad people. There are just people who do good and bad things.
There is a calypsonian called Hunter who has written the essential piece on understanding Dominican and I daresay Caribbean people. The song is called 'Typical Dominican'. Basically it talks to the fact that if a local likes you, you could pretty much kill a third party in front of them and it wouldnt be you and they'd testify to that. On the other hand, if they dont, you are essentially fucked. Doesnt matter how good a person you are, you can give up ghost and just assume the guise of a villain, cause thats what you will be.
Oddly, these same people then turn around and want justice from police and a court system with jurors who are the same way inclined.
Anyway, this habit of taking an instant liking or dislike of people is very common. Pity the young woman or man who dares be different, quiet, individualistic, stylish...name your trait of potential voodoo worshipping non conformist and it is no wonder the migration rates to more liberal lands are growing.
Then again if you want to see why, go to something like the Presidents Charity dinner or any other function when you can see who calls the shots.
Then it will all become clearer.
