What it says is that they wanted to teach people about the religion of islam, while it isnt ok in schools to teach about Christianity, and no it isnt in the op whether or not its proselytism.
It also doesn't say that they're going to be hung upside down by their toes, but I choose to assume that they won't do something like that because it would be wrong, and there's no reason to think that they would. Unless you're hysterically paranoid about Islam.
