You are correct that "dominant language" is, in fact, a legitimate term and can be used in completely harmless ways. But, dominant language refers to an individual's proficiency. What language do you dream in? What language are you more proficient in? That's your dominant language. What you said, however, was that English was not the "dominant language in Miami." Then you went on to say that "these people can't communicate" with the rest of the country, ignoring the fact that an individual can speak multiple languages. Your usage was basura and myopic.
Since you claim to like facts, per ta 2015 Census report, there are 128 different languages spoken in the homes in the Miami metropolitan area (tri-county). Instead of assuming these people are any less culturally American based on language or trying to figure out 128 different countries it would make more sense for certain Miami neighborhoods to belong to, maybe appreciate the fact that Miami is the only city in the United States where the most studied language is English. Perhaps you might actually respect the fact that this signifies many individuals in Miami are working hard to communicate (in English) with their fellow citizens.
As for trying to all me out as a bigot (for calling you a bigot) because all you were saying was that "Spanish-speaking people have more in common with each other than they do with English speaking people:" (1) your (new) generalization is false and paints with too broad a brush; (2) that's not all you said, you poor, poor fool. You had just said, moments earlier: "Honestly Puerto Rico and Miami should just become their own Caribbean countries. Neither really belong in the US imo."
Also, just for fun, please compare the highlighted quotes above to the previous group of highlighted quotes. You previously said "half the people" in Miami can't communicate with the rest of the country. Now you're admitting that was a made up statistic.
