True, but at some point, parents have to take responsibility to teach their kids how to deal with such matters. A teenager is certainly old enough to learn how to understand that there are lies out there, and that these lies hurt people that we are told to reach out to and love.
I hear you. It is tough, especially when the kids are impressionable and easily manipulated. But we have to take responsibility, be involved, know our kids' friends. It is not enough to assume that the Christian school or youth pastor will disciple them...we have to be the ones who take the lead.
