"And if you're a parent who thinks you're okay because your kid doesn't have a phone or iPod yet, and/or you've used all the parent controls to filter out explicit material, you're not okay. The filters are tissue paper and your kid without a phone is on a school bus or in a locker room or at a public park with phone-equipped kids every day. And they're like all kids in exploring - by whatever means available to them - exactly what their parents are treating as too embarrassing or taboo to talk about."
