You really must read the entire post, but I'll give you this tease:
Besides, for Mickey to talk about unsteady judgment strikes me as a little rich. Hands up who can now recall whether Mickey was for the war or against it? Was he for Kerry or did he loathe him? Is he for gay marriage or against it? This is a man who cannot write a sentence without fifteen parentheses for qualifications, internal rebuttals, self-questioning, meta-meta-spin, obscure references to people he might once have dissed or who might have dissed him, and even an imaginary editor to subvert his own points even as he makes them.
This isn't just towel-snapping anymore. This time, it's personal.
Kaus's baiting has been so demonically successful that he has even succeeded in prompting Sullivan to pop off against Glenn Reynolds, Power Line, and the Belmont Club. (And the ease with which Sullivan does so suggests that he's been spoiling to to claw at these other blogs for some time now. Either that or he's just very facile at tossing off casual, personal insults. I report. You decide.)
Update, 11:13 p.m.: A commenter notes that Sullivan used to refer to Instapundit (his "blog hero") as "Glenn." Now that he's a partisan dupe, he's "Reynolds." I wonder when Andrew disavowed him.
