Having kids is no excuse to let your brain check out when someone tells you they're in vague, amorphous danger. When those kids grow up, they'll be inheriting a world where civil liberties can be (and have been) eroded by cynical lawmakers playing on their parents' fears of children seeing things that they consider inappropriate.
It's like how more Americans are killed by police than by terrorists, but we "need" PRISM and more SWAT teams instead of better police training. Children are in far more danger of living in a nanny state than having their lives ruined by online pornography.
