I'm with her on this one, but at the same time, you have to be sensitive. These are children's minds. They are undeveloped. They don't deserve to really know these things just yet; maybe in the teenage years, yes.
It's the same thing with the sex ed programs. They're teaching them younger and younger these days, allowing children to think, “Hey, look, I can think like an adult. I'm learning about stuff that adults know.” It's making them comfortable—too comfortable. I believe education should be there, but it should be very sensitive to what the child's mind is, because it is undeveloped.
