You can bet Cain who isn't bound by political correctness wouldn't be tolerant of forcing high school students to recite the pledge of allegiance to Mexico in Spanish, or say that it was ok to tell US students that they could not wear US flag t shirts on May 5th because it might offend certain students.
That pledge and song were in one class, a *Spanish* class. The students were learning a language.
In high school, my husband was in French class. They learned “La Marseillaise.”
