I don’t think the question is whether Jesus is violent or peaceful, or whether Allah is violent or peaceful. The question is whether Christians are commanded to be violent or not, and I think we all know the answer...
The Great Commandments are to love your neighbor as yourself and love the Lord with all our heart, mind, soul and strength. I wish there were more Christian extremists, who take the words of Jesus literally, and act them out on a daily basis.
However, no one hopes for more Muslim extremists. No one hopes for more Muslims to take the Koran literally.
p.s. Jesus has the right to be violent, because the universe is His posession, and He can do with it as He wishes, including killing people, and sending them to hell.
