The war thing....
When we send young men and women into harm's way, we have a moral obligation to protect them whether or not we believe in the cause.
We are free to protect them in any lawful way that we choose or we can choose to do nothing.
Convincing Terry Jones to STFU would be one way and I think that that is actually happening now.

On the cult thing...
I don't know if Jones is breaking any laws but it does sound oppressive. Here is a quote from the Post article :

"Long before Rev. Terry Jones threatened to burn a Quran, former parishioners say he presided over a church that he treated as a personal fiefdom, imposing a strict orthodoxy that tore apart one Gainesville family after another.
Congregants are required to vow allegiance to Jones....
Two of his daughters have left the church in disgust."

Jones has a history of three decades in Germany "creating his own empire" there as well.

So we have medieval societies and modern societies functioning in parallel.
Looks like war is the chosen means of communication.
