You got voted down, but this is absolutely real. I speak multiple languages, but none with the nuance and clarity of context as I do English. I communicate with folks all across the world that are all English speakers, however, the variance in comprehension is so drastic that at times we're really not using the same language, even if we're using some of the same words.

If you emigrate to a country, it's a reasonable expectation that you'll learn the language. The United States doesn't technically have an official language, English is just de facto, but from a practical standpoint it's absolutely occupying that role, and will in perpetuity.

I can absolutely agree with the premise that being frustrated with language barriers isn't racism, it's an actual real and realized impediment to understanding.
