As a high school teacher standing in the halls during class changes and working with these young people every day, I am not sure that what is offensive to some parents would even cause a student to bat their eyes. They have all seen an MTV music awards show after all. Most have become numb to sexually explicit material or material that may be offensive because of social media and the need for artists of all types to push the envelope in order to be original and the next big thing. Shouldn't we be encouraged by the fact that they experience this literature and these issues in the safe enviornment of the classroom with educated individuals that can help them bounce their ideas around or get answers from? I am a math teacher, who is not as well read as he should be, so forgive me for not being eliquent, but I know I do not have all the answers and definately need help with exposing my son to different view points so he can form his own decisions and become a well rounded individual.  Trust us teachers to know and do what is best for the students.  Some of us spend more time with the kids then the parents do and know how to approach subjects with the individuals that we have had the time to develop trusting relationships with. If there is an issue, handle it on an individual basis.
