The daughter is now an apostate of Islam.
It is only proper that there be a lesson 2: the students being informed that they are now Muslim and if any deny their new religion they be told that apostasy is punishable by death by beheading. I think the public executions should take place on the playground following the noon prayer. Parents invited.
The daughter is no more Islamic than you who read the words of this article and in essence recited the nonsense words in your head just by reading. The God of Abraham requires belief and not mere words or even the motions of baptism.
But if you believe otherwise, that is on you.
There must not be a lot of Christians in that town.
