Actually it should still be the parents job. They are their children, not mine. I know when I was a kid I knew that "I" was the one who would get in trouble if I was doing something I wasn't supposed to. Sure access to some media is easier nowadays with the internet. But any kid who really wanted to could find a way to access dirty magazines, or alcohol, drugs, whatever back when we all were kids. But I knew if I got caught it was my hind end that was going to get tanned, my parents weren't going to go whining to some hotel clerk.
And while I don't know anything about filters I'm pretty sure they could buy just a pornography filter if they were that worried about "the children". The only reason I can think of anyone not wanting children to look at "gun sites" is because they are rabidly anti-2A and want to brainwash children. It isn't like they are going to get hurt because they read about the muzzle velocity of a 220 Swift!
