It's true there are a few rules on this site. But it's Shon's site, and I think courtesy binds us to respect the customs he wants observed. Just like I would be willing to do on a French site that asked users not to, say, disrespect the dead at Verdun.
If your deep desire is to make fun of the victims of 9/11 or the U.S. dead in Iraq, you can always do that on the forums of the newspaper Le Monde (lemonde.fr).
