Who said anything about DU being something to worry about? Many of us see them the way PJ-Comix sees them, as a busy little (sort of) ant farm, a source of laughs.
We can still laugh at what they say, without laughing at them directly. They are sad, mentally ill people that need some serious psychiatric help. But to say that we can't laugh at their statements is TOTALLY different.
So, what's the obsession posting about them? Who cares?
