And besides, FreeRepublic is a powerful force for conservatism on the internet. They can't allow FReepers to advance and promote freedom of speech that follows a conservative agenda.
The enemies of the State will use every tool at their disposal to destroy the State.
Go to smokinggun.com (is it thesmokinggun...). They printed the full Al Qaida training manual. It told their terrorist agents how to tie up their case in the courts. The same legal structure they seek to destroy.
A terrorist organization that operates outside the law deserves to only be shielded by law to screen out innocent individuals. They fight for an army wearing no uniform or even the garb of emergency doctors and police. They violate Geneva conventions as a matter of course (attacking civilians and doctors).
I don't believe that communists believe in "free speech". They believe in using the tool of "free speech" to preach seditious overthrow of the constitutional government. That is not protected speech regardless of how long they believe it will take to achieve their goal.
