I am David in DC, not DavidinDC. On at least one wiki, there IS a DavidinDC. I'm not he.
I thought you said you were on wikibreak. It's a lie, but not an evil one. 
Your slur against me, your faux retraction, and your reiteration of the lie are all examples of evil behavior. If you change your behavior, the way you're treated will change. Remember, focus on the behavior, not the editor or, in your idiosyncratic parlance, the behavior of the editor's identity. I do not call you a liar. I call your slur a lie. A damnable one.
