There are many, many goyim who would never take a TV into their homes either. Do you know what they call it? An “idiot box”. When my kids finished pre-school I eased them off the tv which they weren’t watching much anyway. I bought them books, tapes, skates and bikes. I did NOT want them sitting in front of a TV or ever watching unsupervised. I told them the TV was my toy, and Mommy bought all these toys for you. They were very busy with their jewish tapes and books and the learned to read very early. They were also very active and athletic.
So you can start when they are young and say, TV is a waste of time and energy. It is much healthier to be outdoors and be active. It is much smarter to choose a book to read than stick your nose into an “dummy box”. You should learn to think for yourself and not let what a “dummy box” tells you influence you, because all they want to do is convince you to buy whatever they are trying to sell.
Try not to get into the religious issues so they don’t have THAT discussion. If they are taught that “WE choose NOT to do that”, which is absolutely true, then that is a choice. They choose to do that, and that is their choice. Who knows, maybe your kids will influence them by shlepping them outside and talking about the books they read and so on. Maybe they will see the foolishness in all the programs they think are so important.
