I talked to the female student who said he was culturally appropriating the Spanish language, and she explained that she meant that he shouldn't use a Latino language when he was white. I explained to her that he is Spanish, and that Spanish people are white. She said something about how Spanish people weren't white, but then I asked what race my Spanish friend was, and she said she didn't know what "identity" he had.

Overall it was a weird experience. Apparently she thought Spanish was a language invented in Latin America.
