FBI data show the Left committed more acts of terrorism than the Right

If you go by the MSM, you would think that most acts of terrorism on U.S. soil are committed by “white supremacists” and Muslims.
Not so.
According to FBI data on terrorist incidents in the U.S. from 1980 to 2005, more acts of terrorism are undertaken by the Left, instead of by the Right, and terrorism by Jews is more frequent than terrorism by Muslims.
In the pie-chart below summarizing the FBI data:

• Latinos, especially Puerto Ricans, accounted for the largest percentage of terrorism: 42%. Some examples: Organization of Volunteers for the Puerto Rico Revolution, People’s Revolutionary Commandos, Armed Forces of Popular Resistance, Ejercito Popular Boricua Macheteros, Grupo Estrella, National Liberation Movement, Armed Forces of National Liberation, Mexican Revolutionary Movement, and Omega 7 (a Cuban terrorist group).
• The Left (“extreme left wing groups” and “Communists”) accounted for 29% (24% + 5%) of terrorism. Examples of leftwing terrorist groups are the Revolutionary Communist Party, Revolutionary Communist Youth Brigade, Communist Workers Party, United Freedom Front, Revolutionary Fighting Group, Armed Resistance Unit, Red Guerrilla Resistance, Earth First Organization, Animal Liberation Front, Earth Liberation Front, Earth Night Action Group. Some Puerto Rican terrorist groups are leftwing, which would make the Left accounting for way more than 29% of terrorism.
• Jewish extremists such as Jewish Defenders and the Jewish Defense League/American Revenge Committee accounted for 7% of terrorism.
• Muslim extremists accounted for 6% of terrorism, including Al-Qa’ida and International Islamist Extremists.
• The remaining 16% of terrorist incidents were committed by various groups that include right-wing and white supremacist/neo-Nazi groups and individuals, such as Timothy McVeigh and Terry Nichols, Eric Robert Rudolph (who bombed abortion clinics), Aryan Nations, the Justice Knights of the Ku Klux Klan, and Sheriff’s Posse Comitatus. In other words, terrorism by the Right accounted for less than 16% of terrorist incidents.
