Dayuuumnn Dark, that's pretty harsh. you must have been done pretty badly at some point.
I cannot let you slide, because you made several blanket statements which are not true of all dominicans. How can you possibly assert that all dominicans are lazy, stupid, and ruthless? That's just plain wrong.
My first trip to the country was in 2008, to Santiago, and SD. As I've recounted before, my rental car was stolen from the parking lot of my hotel, along with my passport, that of my fiancee, and other valuables. I became very well aquainted with the inside of the police station.
At that point in time, I was totally unfamiliar with dominican culture.
So, what do I do? I stay my fat azz away from SD as much as possible, visit other parts of the island that are not as entrenched with tigueres, am very careful of who I associate with, and learn as much as I can about the culture and people.
Only problem I've had since, was being pulled over for not wearing a seatbelt.
I may be wrong here, but I think that your attitude and arrogance may play a large part in your negative experience.
