I think that framing skips some history.
Less than 100 years ago, immigrants were absolutely pressured to integrate and they were also criticized for not doing it fast enough. Italians, Irish, Jews, Germans all were accused at different points of not assimilating, not speaking English “properly,” not fitting the culture. That tension isn’t new.
And today’s immigrants do integrate. Second-generation language shift data consistently shows English becomes dominant by the second generation in the U.S. That pattern hasn’t changed much in a century.
Also, performing in Spanish isn’t “anti-American.” Spanish has been spoken in parts of what is now the United States longer than English has. Puerto Ricans are U.S. citizens. Millions of Americans are bilingual. That’s not forcing adaptation, that’s demographic reality.
The NFL putting a global artist on a global stage isn’t celebrating anti-American anything. It’s reflecting where the audience actually is.
We can debate taste. We can debate whether the performance was good. But calling multilingual America “anti-American” ignores the fact that this country has always absorbed new cultures, adapted, and evolved.
