Not at all. A lot of the Mexican people in Miami, (from D.F) speak excellent english, went to better schools than I ever will. Mostly everyone speaks English, Cubans, Venezueleans, Dominicans, Argentinians, Colombians.
You could party at a club that was almost all black if you wanted to, and go to a latin bar afterwards, or go somewhere really mixed. I was walking back to my hotel from in South Beach, like around 12th, Esme, and there was a few guys shooting dice and playing Kevin Gates, I love that kind of shyt, I feel right at home, some girls twerking in front of cars.
But, you walk a few blocks up and you are away from anything even close to that, like 30th and Collins. It's a gorgeously diverse place for women, but for everything.
