Looting, flogging, and kidnapping civilians aren't terrorist tactics? John Brown was a terrorist, Lysander Spooner was his advocate.
Back that up!
In a broadside printed in 1858, Spooner spelled out how such a right could be exercised. First, groups should form in the North to send arms, aid, and even to fight in the South. Groups of Black citizens in the South should also "form themselves into bands, build forts in the forests, and there collect arms, stores, horses, everything that will enable them to sustain themselves, and carry on their warfare upon the Slaveholders." Such guerrilla forces could (until the anti-slavery forces were strong enough for outright war) capture, strip and flog individual slaveowners, in front of their slaves in order to undermine the master’s authority. These forces, North as well as South could live by robbing the slaveowners.
"The state of slavery is a state of was, in this case it is a just war, on the part of the negroes - a war for liberty, and recompense of injuries; and necessity justifies them in carrying it on by the only means their oppressors have left them. In was, the plunder of enemies is as legitimate as the killing of them; and stratagem is as legitimate as open force."
It's 1938. If independent elements in the U.S. had advocated and supplied material and
ordnance to Jewish guerillas in Nazi Germany to conduct guerilla operations that
included a plot to kidnap or kill Hitler (a civilian), would that have been "terrorism?"
Government officials are considered hard targets in wartime.
