I’m guessing that “Allahu Akbar” won’t be one of them.
“Allahu Akbar” is allowed. “Christ our Lord” is banned ...
People ought to chant, a’la some old Popeye cartoons that depicted him bashing Arabs, “Salami, Salami, Baloney”.
You have to admit that getting one side to chant “Allahu Akbar!”, and the other side to chant “Deus Vult!”

Once the schools administrators go over their initial freak out, they would look up the meaning of Deus Vult, and have another freak out. Then when the ACLU showed up to complain about “God Wills It!”, but *not* “Allah is Great!”, they would have a third freak out.
