Activism

Two of the band's members, Benji Madden and Billy Martin are active vegetarians. In the past they actively supported PETA's animal rights campaigns. Members of the group recorded a track, "Lifestyles of the Rich and Famous", on PETA's Liberation CD and appeared at PETA's 25th Anniversary Gala and Humanitarian Awards Show. Group members have also demonstrated against KFC’s treatment of chickens. PETA and the band had parted separate ways when news emerged that the band's partners are pro-fur.
Good Charlotte has shown support for Washington, DC punk and youth activist group Positive Force D.C. on multiple occasions. In 2004, the band organized a special benefit show for the group. The show raised thousands of dollars for Positive Force which was also shared with the D.C. Area Books to Prisons Project, Prevention Works! Needle Exchange program and We Are Family - a DC based advocacy and service provider for low-income seniors in D.C. neighborhoods.
The twins have also posed for the YouthAIDS Aldo "Aldo Fights AIDS" dog tag campaign. They stand side by side, eyes shut, on the "See No Evil?" dog-tag packaging. Joel holds his hands in prayer, whereas Benji's face is contorted and angry and his hand is in a fist.
Good Charlotte also supports the fight against AIDS, as shown in the design of a t-shirt designed by the band's guitarist, Billy Martin, for the H&M Fashion Against AIDS campaign[7]. The t-shirt displays a couple under an umbrella, protecting both of themselves, as a metaphor for using protection.
Good Charlotte will also be appearing as a guest star on Nickelodeon movie iCarly: iGo to Japan.
