I called in today, and checked out the article you pointed me to. I haven't found your 80% of terror incidents commited by Right wingers. Where did I go wrong? All the incidents are posted on the bottom and one of us cannot do the math!!! Is it me or you? Infact in the middle it says this.
Beginning in the 1950s, the most serious domestic terrorist threat shifted to leftist-oriented extremist groups that generally professed a revolutionary socialist doctrine and viewed themselves as protectors of the people against the adverse effects of capitalism and U.S. foreign policies. Some of the more sensational terrorist events during this latter period included the November 1, 1950, attempted assassination of President Truman at Blair House by two members of the National Party of Puerto Rico. On March 1, 1954, members of the same group opened fire on a session of the U.S. House of Representatives, injuring five congressmen. The 1958 commandeering of a Cuban airliner in flight from Miami inaugurated a decade of hijackings by Cuban revolutionaries.
