Yeah, Ricans aren't the only hispanic race, but Ricans and Dominicans (I'm both) are the majority of hispanics in NY...especially the majority that are classified as "ghetto" or "dangerous". You could include Central Americans in that grouping too I guess but they aren't too large in numbers...but most of the South Americans I know don't get the same classification as us by street walkers because they tend to dress different in South America and a lot of them are more Anglo looking.
But there is no doubt that Blacks, Puerto Ricans, and Dominicans have the worst rep in the city. Hell, half of the hispanic immigrants to NY watch the news and are scared sh*tless of us because the media is so biased. I won't deny that ppl of these descents don't do some dumb **** but that's no reason for anyone to generalize.
