Such a list is nice, but unwieldy.
Think for a minute. Who wields the most situational power in the DUer's universe?
Victims, that's who.
You must begin your career at DU with impeccable credentials of powerless victimhood.
That's your ticket to status on that board. Forget knowledge or a sharp mind, the less you know and the more you emote (in the proper PC mode, of course) the better off you are.
And who better to screed at injustice than a perennial victim?
Just go to any radical web site (blacks and Palys are chic) and pick a first and last screen name of obvious ethnic origin. Combine them, and you're done.
If you have the skill, or are the proper sex, an added victimhood point can be gained by portraying a female of the approved victim groups.
If you dare, and have the expertise to handle it, you might consider adding a disability to your character, preferably one brought about by the policies of the mean-spirited, uncaring, planet-raping Repugs.
Hope this helps .
