Fonda fired off a message on her Web site accusing QVC of bowing to a boycott campaign organized by unnamed right-wing groups.
"I am, to say the least, deeply disappointed that QVC caved to this kind of insane pressure by some well-funded and organized political extremist groups and that they did it without talking to me first," Fonda wrote.
The Hollywood Reporter said Sunday that QVC recently began getting calls from members of the public vowing a boycott of the network in the state of Florida should Fonda be allowed to appear.
Fonda, whose opposition to the Vietnam war was well established, has also spoken out against the U.S. invasion of Iraq. She took umbrage, however, over doubts about her patriotism.
"I love my country," Fonda wrote. "I have never done anything to hurt my country or the men and women who have fought and continue to fight for us."
