I understand that we don't have to do what we do for them, and I understand that giving the people who are trying to kill us in the name of their religion their religion's holy book is ironic at best, but I don't think it is right to mistreat it. Just like I would take offence if someone flushed a bible down the toilet, they can take offence to us mistreated their holy book.
I think that we are retarded for giving it to them in the first place, but that is a whole nother subject...
