God help us if protesting the government is ever considered "subversion and espionage".
God forbid others would be as blind as you.
Protests are protests, what they are doing goes beyond that and intends to hamper the military. Just go read their websites.
You need to get a grip. The groups under watch are very pro Palestinian, very pro South American subversive (Marxist) radicals, very pro Philipenes insurgents... you name it these folks back it if it's anti-U.S. or it's allies.
They are very sympathetic to the idea that the U.S. is the problem in Iraq. That should tell you what you need to know.
A.N.S.W.E.R. is one of the groups. Spend a few hours checking out their web sites and the people they network with.
God help us when subversion, espionage and sabotage against the United States is considered little more than "protest".
