I think Judas, the only guy from Judea, was a thief at heart and had an outward character such that the other disciples didn't immediately suspect him when Jesus told them that one of their group was to betray him. That doesn't portray a "terrorist" to me, it portrays something different. A mole. A great deceiver.
Y'know, the disciple that I'd always felt would tend to be accused of being more of the terrorist-type would have been Simon the Zealot--the Zealots were a group of very political "zealot" Jews who were working to overthrow Rome. Zealots were radical; no doubt he was hoping hard that Jesus would boot out the Romans and begin reigning ASAP. Here's where terrorism is waiting to spring forth.
What about James and John, the Sons of Thunder? Didn't they want to call down fire from heaven onto a Samaritan village that refused to welcome them as they went on their way to Jerusalem? Jesus rebuked them for this thought.
Peter cut of Malchus' ear. Jesus rebuked him, too.
Jesus looked with compassion on the people. He wept over Jerusalem.
I guess his 'terrorist' side led him to clean out the moneylenders and merchants from clogging up the Court of the Gentiles, and also calling the Pharisees and Saduccess vipers. I think he'd have called the GB vipers, too, don't you? (Yahoo! I'm sure he would.) Jesus never strikes me as being smarmy, too-careful, unreachable, or trance-like (like Bin Laden). I'm sure he laughed when he held children on his lap to bless them. He wasn't afraid of getting snot on himself.
It seems to me that we always seem to reframe things according to fads. Terrorism is a hot topic/fad now, so it seems to me that everything must now get reviewed in terms of terrorism, and everyone can be measured as to being a terrorist. I think it looks very silly sometimes. Until recently, no one ever thought of accusing Jesus (or even Judas) of being a terrorist before. Ten years from now, i hope no one will think this could ever have been a serious topic... It will go the way of so many other wild speculations...
(Perhaps Jesus appears a terrorist in that in the Bible he keeps making demands of us individually, and some of us don't like/agree with/believe them. Turning him into a bad guy is one way of getting us off the hook of having to deal with any his claims/demands.)
That's how I see it, anyway...
