From a June 24 Examiner.com article:

Right wing talker Michael Savage vowed yesterday during his broadcast that he will retaliate against media watchdog Media Matters for America by posting pictures and “pertinent information” about the organization's staff on his website. He made the comment almost in passing during one of his infamous rants, but did not explain what he expected his followers known as the “Savage Nation” to do with the information.

Against this backdrop the threat to post pictures and personal information about media watchdogs as a response to criticism can legitimately be perceived as a threat. Michael Savage may be famous for brash talk and incendiary language, but recent history must be taken into account as his “Savage Nation” may take the talker's inflammatory posting as marching orders to take action against his enemies.
