Do you REALLY want to know what I think? Well, then here it is. This is only MY opinon, and what I choose to do. YMMV.
Here are a few key lessons years of teaching high school and dealing with teens have taught me:
I would rather teach my teen to know right from wrong, and be able to think for herself and react effectively to an questonable situation than to shelter her from anything "inapproiate". Why? Because there will come a day, and no matter how much you shelter them it WILL come, when thay are going to be faced with all of this "inapproiate" stuff in real life. For most it is LONG before they are 18. If you don't believe me, then spend just one day in a high school fading into the background and really listening to teen conversations when they think you don't hear. They are faced with sex, alcohol, and myriad of other potential pitfalls EVERY DAY. What they watch on TV is the least of your worries. Kids who are sheltered form everything, and whose parents do their best not to let them be exposed to anything "questionable" have NO clue how to react and are much more likely to get pulled along with the crowd or give in to the first boy who shows interest becuase the KNOW they are different form thier peers and are just trying to fit in. Kids whose parents actually allow exposure to the "questionale" in life and discuss how to handle is are confident in themeslves and and usually do fine.
I know many will likely disagree with this, but I spend 7 hours a day emmersed in teen life, and have wached countless children go through this. I WON'T be raisnig DD in a bubble and policing her every choice and move becuase I have seen the disaster that can result. I want her to be armed with the confidence to do the right thing. That means I have ot relinquish some control and allow her to make her own decisions, not the least of which is what she will watch on TV. I just have to wonder what else parents are policing if a 14 year old cannot even watch and R rated movie, and what the consequences of that will be.
This is not to say that I won't be involved in her life, know where she is going, and who she is spending time with. I will however be letting her make her own decisons in as much as I can. I cannot be with her every minute. If she cannot pick her own TV shows, then how is she going to pick her own boyfriends? Make the important decisons like when to have sex and with whom? Sould I go ahead and get palstered because everyone else is? Becuase wether you realize it or not, the vast majority of teens are fraced with these decisons, even at 14. If they have never been exposed to the realitys of life, not even on those "inapproiate" TV shows, then how are the supposed to make mature informed decisions about them?
I think there would be less of all the things you listed if there was an open and honest dialouge going on about the fact that they exist, nad how to deal with them rather than an attempt to shield our children from any mention of them.
