In addition to anti-war activism, ANSWER is involved in advocacy for rights for undocumented immigrants, believing that all immigration should be legal. ANSWER became involved in immigrant rights activism through protests against Save Our State, a California-based anti-undocumented immigration protest group, and the Minutemen Project, a group which patrols the U.S.-Mexico border to prevent illegal border crossings, and which ANSWER views as practicing racist vigilantism. These protests began soon after the founding of the Minutemen group in April 2005.
