Charles Johnson gets libel happy

Charles Johnson, king among the Lizardmen, is contemplating suing Indymedia(http://littlegreenfootballs.com/weblog/?entry=8694_Indymedia_Libels_Me_Again) for a satirical article on its open-posting newswire alleging he had been arrested for paedophilia.
The Indymedia article is in bad taste and, depending on the libel law you apply, clearly defames Mr Johnson with the claim that he "was charged with 3 counts of Sexual Interference, 2 counts of Invitatian to Sexual Touching, and 1 count of buggery".
However, while Charles is keen to protect his own reputation against defamatory lies, he apparently has no problem hurling accusations at his own enemy. In his latest outburst (http://littlegreenfootballs.com/weblog/?entry=8695_AP_Bias_Gets_Worse_..._Much_Worse), he accuses AP journalist "Charles J. Hanley and his employers at the Associated Press [of being] very clearly, on the side of the jihadis". Basically, he is accusing them of supporting attacks on US troops and international and local civilians in Iraq. One wonders what AP might have to say about this? Or are such accusations protected under the First Amendment...?
