According to this we should all be plastering little disclaimer icons all over anything we put on the interenet informing those who can't identify the obvious that something is 'civil content' or not.

That's great, next all we need is an Ayatohllah of the internet and then maybe we'll also take a hint from the PRC and start stealing people from their homes and chopping their balls off for saying "I disagree with the president".

Slippery fucking slope, Tim.

We already have a way of warning someone if something is offensive: ever heard the term NSFW?
