Minnesota Public School Promoting Islam?

RebSaint said
There's a categorical difference between "teaching" about a certain religion and promoting a religion.

The article really doesn't describe if the teacher did indeed cross the line by promoting Islam--or if someone misinterpreted "promotion" for "teaching"

I teach about all kinds of religions in my classes; I take great care to impart to students that I'm not promoting any one of them.

Christianity can be taught in the public schools as long as it isn't being promoted or "forced" in any way; same with Islam, from my perspective.

Yes, there is a difference---I was merely borrowing language from the article in my title. This would indeed be indicia of promoting Islam:

TIZA has many characteristics that suggest a religious school. It shares the headquarters building of the Muslim American Society of Minnesota, whose mission is "establishing Islam in Minnesota." The building also houses a mosque. TIZA's executive director, Asad Zaman, is a Muslim imam, or religious leader, and its sponsor is an organization called Islamic Relief.
Students pray daily, the cafeteria serves halal food - permissible under Islamic law -- and "Islamic Studies" is offered at the end of the school day.
