No, nothing will change at DU since the line there could be described as venomous Stalinism. There was only one time that I noticed a thread on DU agreeing with the FR, and that was the outrage over the Kelo v. New London ruling. Afterwards though I think the masters at DU cracked the whip. "Stick to the party line, you must support diversity", yet oddly no diversity of thought.
You may have also noticed here that topics are not limited to politics, but also science (some good astronomy and geology threads), history (SunkenCiv's ping list), among others. Yet on the DUmmieboard it must have the obligatory
HATEBUSHHATEBUSHHATEHATEHATEBUSH. It's just not healthy over there. You wonder if their heads are going to explode sometime, they are wound up so tight (of course we get in our flame wars here).
Stick around, you might learn something.
