Many say fundamentalism leads to violence. In some instances this is true. If you took a system of teaching that had violence at its core or some form of elitism inherent within the system, this is often the result. But true, orthodox Christianity should not. The answer to that question is, "It depends on the fundamental".
Christianity, understood properly will not lead one to violence but humility. It is the nature of the faith. It is a fact that "in the name of Christianity" there has been violence and injustice. But that is all it was..."in the name of Christianity"...not true Christianity. At its core is the humbling reality of our need for forgiveness and our undeservedness of it. But by the grace of God, not by our deserving it, Christ came to suffer for our sins in our place. He then tells us to go and make disciples of all nations. But He never teaches this to be done by force because it cannot be. True conversion can only come when God regenerates a heart. Christians should understand that and that fact alone makes us realize our goals can only be attatined by preaching the word...not by force or violence or injustice.
