According to American political scientist George Michael , " right-wing terrorism and violence has a long history in America " . Right-wing violent incidents began to outnumber Marxist incidents in the United States during the 1980s and 1990s . Michael observes the waning of left-wing terrorism accompanying the rise of right-wing terrorism , with a noticeable " convergence " of the goals of militant Islam with those of the extreme right . Islamic studies scholar Youssef M. Choueiri classified Islamic fundamentalist movements involving revivalism , reformism , and radicalism as within the scope of " right-wing politics " . In the aftermath of the '' Brown v. Board of Education '' decision ( 1954 ) , members of a resurgent Ku Klux Klan perpetrated a campaign of terrorism against blacks , civil rights activists , Jews , and others . Klansmen bombed the 16th Street Baptist Church in Birmingham , Alabama , in 1963 , killing four African American girls , and carried out other murders as well , including those of James Chaney , Andrew Goodman , and Michael Schwerner ( 1963 ) , Lemuel Penn ( 1964 ) , Viola Liuzzo ( 1965 ) , and Michael Donald . Between 1956 and 1963 , an estimated 130 bombings were perpetrated in the South
