Should Our Kids Read Books With Profanity?

Some time ago  I received a lot of comments on this blog and on another forum when I posed the question about modesty in dress. About fifty percent of the respondents felt it was okay for women, and men, to wear shorts to church and some of the other fifty percent said they would not wear shorts to church, but they didn't see anything wrong with it. Now I come to another controversial topic which someone else started, and which I felt that as a Christian parent and grandparent I should get involved in. The question was, "Should YA (young adult) books contain profanity?"
