Well, for one, me. Racism even on a joke site is still racist. As far as I'm concerned, and I know I'm not alone, racism is not acceptable in any form.
Almost every joke relies on a some social preconception or stereotype... nationality and race are only some of the characteristics you can choose from. What can you find on that site that is worse than what you can see on South Park or any popular movies? It seems like a double standard that a page (which you have to look for) which contains obviously only bad jokes is somehow worse than half-serious stuff on TV (directly advertised and explicitly approved by a local company).
Jokes aren't racist just because they mention a 'race'. The 'race' in a particular article in the Encyclopedia Dramatica can easily be substituted by another, even an 'opposite', 'race' and the article would still make as much sense. If that is the case, the 'race' isn't an integral part of the joke and it isn't racism.
That's why you don't visit sites like that. No visitors means no money, unless someone is digging into their pockets to pay for the thing (quite possible, of course, and I have no idea how ED gets their money).
