Get it through your overly thick skull. There was no attempt at conversion. Zip, zero, zilch, nada. The teacher is an evangelical Christian using a work book printed in 1995, and use across the country for 20 years.
I read the physical copy of the worksheet. It said, “Here is the shahada, the Islamic statement of faith written in Arabic, try copying it by hand.”
It identified what was being written, and what it meant. Finding the precise translation would be trivial, and in a class of students, it is very likely that the natural curiosity of students would be satisfied. From what I have read, this would be a conversion technique that would enjoy some percentage of success.
It was inappropriate. Every authority figure involved should be fired and banned from any educational role. We have some nice farm jobs for these folks. See that big pile of manure over there...?
I home schooled two sons. We gave them a solid grounding in their Catholic faith. And when they got old enough, long after they learned their catechism, we introduced them to other faiths. I have books on islam, Zen, Hinduism, Confucianism, all around the house. Standard textbooks. Not one of them required reproducing any profession n of faith.
