Why are you obsessing on an issue that is so easily solved for you. Change the channel if you don't like the subject matter or the way it is presented. Don't buy a television if you don't think there is anything avalible that meets your standards or belief system. Read a book you find acceptable for you.
Notice all the above is directed toward you and your needs based on your beliefs. There is no need for you to distress yourself over televisions' presentation or the beleifs of those writing and producing as you have so much control over what you see and what you purchase. Since we all have ourselves to work on and it takes a lifetime (and more) to try and achieve what we each believe God wants for us, you should have little time to stress over the choices of others.
