My take on the horrific attack we sustained 9 - 11 was we were attacked by a "fifth column". Calling them terrorists would give them an edge of sharing common civil rights we enjoy in the USA. If they are a "fifth column", they don't have rights and they can be executed as being out of uniform, as spies, I believe. This should apply to anyone giving aid and comfort to the enemy. In addition, I don't believe we can afford tolorance for the active anti-war behaviors we saw in the Vietnam conflict.
