If a kid is old enough to be lookin' at the porns for purposes other than grossing themselves or their friends out, they're probably of the age where it's officially None Of Anyone's Damn Business. Unless they're, like, inspired to rape puppies by it, in which case I would suggest psychiatric help.

/my two cents.

Is it just me, or does the Great Internet Porn Debate show up every time we start running out of things to wring our hands over for the sake of the children?
