Would that be the same "nonviolent" Jesus who scourged the money changers from the Temple?

"In the temple courts He found men selling cattle, sheep, and doves, and money changers seated at their tables.  So He made a whip out of cords and drove all from the temple courts, both sheep and cattle. He poured out the coins of the money changers and overturned their tables. To those selling doves He said, “Get these out of here! How dare you turn My Father’s house into a marketplace!"

John 2:15

That actually sounds more like a pretty conservative Jew than an "anti-establishment radical", by the way.  

"Render unto Caesar" doesn't sound too radical, either. 

(It was also a good way to keep from getting killed as anti-Roman, of course.)
