I just read a few of them too. I don't know why. Maybe for the same reason as when you have a toothache, your tongue is irresistable drawn to press on it once in a while, even though it gives you a sharp pain. That being said, most of the cretins over at Communist Underground are the most vile, hate-filled, paranoid and childish folks it has ever been my displeasure to come across. Nothing I've ever seen posted on this site even comes close. The whole lot of them over there combined couldn't make a pimple on Ronald Reagans backside. In fact, they'd have to stand on their mama's shoulder just to kiss his ass. If any of them would like to discuss it with me face to face, just quit lurking and PM me and I'll be happy to arrange a meeting.
I used to go to DU until it gave me the irrestitable urge to stab my eyeballs out with a fork. ;~D
