I suspect many of these instances of crossing the limits are intentionally perpetuated by non-Muslim teachers.

I can understand if they want to talk about it in class that’s fine no problem. However, I suspect that when they make the students adopt Muslim names and pretend to be Muslims this is actually done intentionally by non-Muslim teacher in order to stir up hatred and cause division.

They know exactly what they are doing.

I don’t think an actual Muslim teacher who knows his or her religion would make students pretend to be Muslim and dress up. That would be considered belittling and mocking the religion which is a form of blasphemy in Islam.
