Heero there are many such topics that are not muslim related on QL, even the one you mention. Usually all the topics are not muslim related but provided that some one dont twist the topic and specifically attack any religion because of personal grudge it is not for just Islam only as there are people from all religions here on the QL.

Islamic teaching is not supposed to be forced on other religion on some one else, nor radicule some other's religion because we believe that to us be our way to others be their's, nothing to be forced.

All non muslims should have religious freedom in Islamic society and it is the teaching of Islam. These are all the basic manners for the all the QL memenbers to not to offend each in this regard but yes they can discuss any other thing they want.
