Hume’s Ghost explains why he reckons liberal bloggers need to respond to Ann Coulter and Michelle Malkin: http://glenngreenwald.blogspot.com/2006/06/why-respond-to-malkin.html
The only good reason I can think of for responding to their toxic, whacked out diatribes is that these are just the kind of low hanging fruit for liberal bloggers that makes for easy and humorous posting on an off day. Heck, the posts practically write themselves.
But seriously, the argument that Malkin, Coulter, and their ilk should be responded to because they are influential does not hold up in my opinion. They are only influential with the subspecies boobus wingnuttus, and nothing any liberal blogger ever writes will persuade followers of Malkin or Coulter of anything. There are no reasonable people out there who follow these harpies, and none of their followers is amenable to reasoning or persuasion.
This is especially true of liberals whom boobus wingnuttus has been conditioned to revile and distrust. It may be possible for a handful of Malkin or Coulter fans to be turned from the darker side by someone on the slightly less dark side among conservative pundits. But that would hardly be worth the effort.
I hope the left blogosphere will keep making fun of Malkin and Coulter and Fred Phelps and the whole gaggle of right wing nut cases. This has been a source of constant amusement. Nobody beats Tbogg and World O’ Crap for mocking these “people”, and my day is not complete without visiting their sites. But don’t start taking these clowns seriously.
