I have a tv and I have no problem letting my kids watch some pg13 shows/movies, aslong as the homework and studying is done and it is before 9pm.My daughter goes to a very right-winged sunday program and has girls from BYBP in her group. They outright were telling me that they watch hanna montana and wizards of waverly place and high school musical and jonas bros etc…its clean fun-but they were very clear to tell me that if anyone at school found out about it they would be in big trouble at school.They have a tv but it is hidden in the parents room and when they go to a hotel in the summer-apparently every shabbos they would go away-they would watch the whole time!And these are 6 and 7th graders in BYofBP!They know to hide that they watch tv!
Personally, Ithink parents should watch out for far more dangerous behavior like drinking and drugs…tv is harmless but hey thats just my oppinion!
