3. SE is simply doing her job by presenting a counter argument to the other three on the show.
However, what drives me up the wall is when they just sit there and let her blather on and on!!! Why on earth one of them doesn't jump in and at least refute some of her "opinions" is beyond me. I mean I know that with that chick it IS hard to get a word in edgewise, but once in a while she comes up for air...usually a loud gasp. (I think her weird breathing pattern has been discussed here at DU in the past.)
In any case, I think I could take her snotty "I know what I'm talking about" attitude if just once the rest of the folks at the desk would take her on and explain why she is wrong and is just repeating the talking points given to her by the right fringe.
