Don’t try to shield your kids from popular culture. Although it's sensible to filter out and monitor many harmful cultural influences, understand that there is no reasonable way you can completely protect your kids from experiencing the harsh side of popular culture. Realize that even if you could completely isolate them from the culture, doing so could cause them to rebel in protest and "immigrate" permanently from their homeland (their faith) to the foreign place (popular culture). Instead, make it your goal to walk through the culture with them as their guide, helping them develop the critical thinking skills and wisdom they’ll need to successfully confront it.
Get to know today’s popular culture well. Remember that today’s popular culture is vastly different from the culture in which you grew up. Invest the time and energy to venture boldly and purposely into the culture yourself, listening to its music, watching its shows, etc. Learn what types of messages your kids are receiving from the culture. As often as you can, experience the culture along with your kids (such as by watching a new movie together), and when you can’t be with them, discuss the culture with your kids (such as by talking about a current book together). Strive to be constantly engaged with your kids, both spiritually (by praying for them) and intellectually (by helping them think through issues the culture raises).
Read reviews together. After experiencing a particular cultural message (such as watching a television show), help your kids consider such questions as how they reacted and why, what they found appealing or distasteful and why, and whether or not they agree with the message presented and why.
