Molly Ivins
Maybe you remember the late Sue Rockne, ardent DFL'er with somewhat the same "in your face" approach. I agreed not at all with her, but she always spoke with class, suitable humor, and with a big, warm smile on her face. She loved the discourse. The last thing in the world she wanted was an absence of debate.
Molly Ivins fell far short of that mark. She was mean. She got personal, well beyond "typical" ad hominem attack. Her columns were simply red meat for the left, largely void of fact and reason, nothing that would stir debate or change minds. To be fair, the right has some of these people, too, like Michael Savage, and I have no use for them either, for the same reasons.
