Dunno. Those DU folks sound like a bunch of racist haters to me. Are they allowed on Facebook?
Sorry, I regard DU as unfriendly territory, a fever swamp filled with some very concentrated vitriol, and would not venture to allow ANY information about myself to appear in their sign-in procedures. So I have to rely on second-hand information about what they are really talking about over there.
The Orwellian Two-Minute Hate that just goes on and on. Once transformed, they simply cannot find their way back to dry land.
