White terrorists are called Lone wolves. People of color are called terrorists. Other than 9/11, the lone wolves have slaughtered the most Americans. Our policies of colonialism we force on double digit countries, through the CIA, result in the terrorist attacks prior to, and after 9/11. that our government refuses to tell America. Back in the Imperial Roman Empire days, before the jewish priests had the jesus killed by the invading Roman army, there was a slave and gladiator named Spartacus. He escaped and formed an army and fought the invading Roman armies and was finally killed. Spartacus fought an invading colonial power who's purpose was to steal his countries lands and resources, famous and revered enough to have movies glorifying his struggles. 
our occupations are for the same reasons as the Romans, and our CIA created and supplied the terrorists that has attacked Americans. So like the Romans we call them rebels and terrorists, and their own countries revere them.
