Yet Jesus Pbuh said According to the bible : I came by the sword.
No, He didn't. He said:
34 “Do not think that I have come to bring peace on earth; I have not come to bring peace, but a sword. 35 For I have come to set a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law; 36 and a man’s foes will be those of his own household. 37 He who loves father or mother more than me is not worthy of me; and he who loves son or daughter more than me is not worthy of me; 38 and he who does not take his cross and follow me is not worthy of me. 39 He who finds his life will lose it, and he who loses his life for my sake will find it. (Matthew 10:34-38)
It's a metaphor for how not everyone will accept the Gospel and because of this disagreement and discord, people would be set against each other. Those verses are in the context of a chapter that is mainly focusing on Christ warning His followers of the coming persecutions and exhorting them to remain steadfast in their faith.

We could say the same. And say Crusaders follow Jesus words , they too came by the swords.
The Crusades were armed pilgrimages that had the goal of taking back the Holy Land from Muslim invaders and protecting pilgrims. Did the Crusaders do wrong? Sure, they did. They were human and what wrongs they committed are to be condemned. However, what wrongs they did went against their mission. They didn't only do bad, anyway. The Crusades were an effort to protect Christendom. The Middle East and North Africa were Christian before the Muslims invaded those countries.
And this could be proven historically by how violent christians were through the history.
Not only the past, but even today and recent past. George bush a devote christian saying he will do crusade against muslims. I could now say to you: well christianity is not really peaceful religion when someone looks at all these evidences. Or how about Terrorist Brelvik who says to be proud christian? You cant claim to be peaceful catholics when we know how Arians were destroyed by the swords and any christian sect that opposed the belief system of Nicene Creed.
Your attempts at deflecting from Islam's history of violence by beating the dead horse of Christian wrongs will not work with me. Look to the teachings of the religions and you'll see which were being true followers of Christ and who were not. Do the same with your own religion.
The difference between islam and christianity in my humble opinion is really monotheism. Christianity has difficult and unclear version of monotheism. I read stories of converts who said they left the religion because of trinity.
Wrong. We are monotheists. Your ignorance of the Trinity doesn't change that. I could explain the Trinity to you if you want.
