Excuse me for noting this, but the link you provided here does not support your assertion, and the organization you cite was not mentioned in the referenced article.

Organizers for two of the rallies were noted, but neither of them is the Workers World Party you claim organized "recent anti-war protests," without detailing which ones.

"Demonstrations continued the following weekend. On Nov. 3, hundreds rallied at an anti-war protest outside MacDill Air Force Base near Tampa. The protest was organized by the African People's Socialist Party.

That same Sunday, thousands of young people swelled the ranks of 15,000 New Englanders protesting the war on Boston Common. Speakers included actor Tim Robbins, Howard Zinn, and Boston City Councilor Chuck Turner, who urged participants to demonstrate in Washington on January 18-19. The rally and march were sponsored by United for Justice with Peace."

(my emphasis)

It may have escaped your attention, but a news organization can report on an activity without being involved in its organization. That appears to be the case here.
