Protecting our young uns?
You know, I can (barely) remember being a teenager, and I don't remember ever, ever, hoping to be 'protected' from the possibility of viewing smut.
Actively seeking it out in order to ogle now, that's quite another issue.
How long should we protect children from learning there is unpleasant stuff in the world? Their 30s? 40s? Hope they die without ever learning what those naughty things in their keks are able to do?
