You have a misunderstanding of the word ‘violent’.
Jesus was not violent and never espoused it period.
Actions which you call ‘violent’ were not violent. Cleaning the Temple of money changers was ‘cleaning’ the Temple and not an act of violence against the violators of the Temple rules. He was enforcing the rules not advocating physical bodily harm.
To stretch Jesus’ actions of defense and enforcement into acts of ‘violence’ is hysterical and false.
You also have a misunderstanding of the
biblical terms translated to ‘sword’.
The word ‘sword’ came from two different words having different meanings. One is a metaphor and was used to denote ‘the Word of God’.
“And take the helmet of salvation, and the sword [machaira] of the Spirit, which is the word of God” (Ephesians 6:17)

John 2:12-22 "... So he made a whip out of cords, and drove all from the temple area, both sheep and cattle; he scattered the coins of the money-changers and overturned their tables. ..."
Sounds pretty violent. This wasn't going table to table having persuasive theological discussions.
And the other time Jesus talked about swords he meant the stabby slashy kind. “Let he who hath no sword sell his cloak and buy one.”
