...I've got 2 daughters, both teenagers. You bet that we are filtering, what they are exposed to. However, isolating them from everything that we may consider "dirty", "ugly" or "undesirable" is, IMHO, not the the right way to go about it (and won't work anyway, unless you lock them up in their rooms at home). Isolating them from everything "bad" and "ugly" will not prepare them for a life on their own, will not open their minds, will not make them ready to stand on their own,and to make reasoned, considered choices and to decide on their own, what's good and what's bad, what's right and what's wrong for them, once they venture out on their own. Feeding them a controlled dose of "real world" and helping them to ask the right questions, and to think about things and make a considered judgment, is IMHO the better way to go.
