A March 14 NewsBusters post by Scott Whitlock is yet another liberals-were-on-my-TV complaint, this time attacking two experts brought on by ABC to discuss the Japan earthquake and tsunami.
George Stephanopolos, Whitlock complains, "didn't identify the leftist background" of Joe Cirincione or Michio Kaku. At no point does Whitlock have any problem with what Cirincione or Kaku said -- this is purely an ad hominem attack.
Further, it's not clear that either of these people are "leftist." Whitlock complains that both Cirincione and Kaku have opposed nuclear weapons, but he doesn't explain why such a position is "leftist." Whitlock goes on to attack Kaku for having "a radio show on Pacifica Radio," but he also has another radio show that is syndicated by Talk Radio Network, which is the home of such rabid right-wingers like Michael Savage and Laura Ingraham, and he has repeatedly appeared on Fox News.
Ad hominem attacks aren't media criticism, of course, but Whitlock and his Media Research Center cohorts seem to be unaware of that fact.
