>"The best move is to teach your children how to not be victimized."

Your GP advocated world-building a child's physical environment to avoid digital - which is simply unrealistic for their later years as it is, and coddling them so nothing that could even potentially victimize them in the digital world would be able to reach them. So, genuinely: What's it gonna be?

Are you going to teach a child the real-world application and use cases for being responsible for themselves, not becoming victimized and carrying themselves well, and learning to act appropriate in an increasingly-digital world; or not?

Otherwise; saying you'll teach your kids real-world application for being responsible for themselves and not being victimized, and then not giving them a space to see the importance of those practices out of fear that they'll succumb to it, is having your cake and eating it, too.
