Certainly that's the case in various concert venues today, and I expect that to continue. These are not entirely new problems. But that's no less true of the past than it is today. I grew up as a young child in the 60s in a world where, if my parents had been as passive about race as today's parents want to be about TV, I would have grown up with Jim Crow attitudes. Because that was the dominant culture.
Parents just have to take a certain amount of responsibility for raising their children.
And they can't expect or demand that the world is going to operate as if everyone is a child. They can't put a television in their child's bedroom and subscribe to every cable channel, and then expect that somehow someone on the other side of the country or the world is going to make sure that their child never watches anything that's inappropriate. That seems to be the logical place to start. Put it somewhere where you can observe it. Otherwise, they would never be able to grow up.
