I think some of you are blowing this into something way bigger than it is.
If you are living under someone else's roof then they have some say in what goes on their home. I don't allow people to smoke in my house, its my house and its my rules.
This is not a exclusive to JWs either. There are still plenty of parents who would not allow their children to share a bedroom with ther boy/girl friend when they visit.
No Apologies
