Negro is the Spanish word for the color black. This bronx bilingual teacher got fired for using the word in the context of colors while speaking Spanish, and it was not used to describe any persons of color. By the way, the teacher is black. Negro is not a bad word, it describes a color.
Wow that’s crazy.
