What is the more violent religion Islam or Christianity?

In my opinion I think that Islam is much more violent than Christianity. When the Danish cartoons came out hundreds of thousands of muslims protested and they even burnt down the Danish emby in Syria. We see A lot of criticism to Jesus all the time but you don't see all these Orthodox Christians rioting in the street or burning down embies. That combined with all the terrorist attacks in the name of Allah and that many of the Muslim priests actually preach violence against Jews and Christians makes me wonder if Islam is really a religion of peace as Muslims say.
