Peace be with you.
You won't win the argument because the truth is Christianity's focus is love, both of God and neighbor. Whether you believe in Christ or not, Christianity "teaches" man has fallen and evil, in this case man acting without God, is the cause. Jesus' Sermon on the Mount...Blessed are the "peacemakers" is probably the most famous reference to Christianity's teaching on peace.
That's true. There are also lines about not responding to violence with violence (turning the other cheek), giving away all of your possessions and allowing god to take care of you, and about treating the poor well. There are also lines about how Christ brings not peace, but the "sword", and to divide families and friends. (Matthew 10:34). You could point out how modern Christians have been instructed to keep all of the old laws, which include things like stoning disobedient children.
Personally, I like to point to the various ways Christianity has been used to justify some of the greatest atrocities of the last couple hundred years, from slavery:
"With regard to the assertion that slavery is against the spirit of Christianity, we are ready to admit the general assertion, but deny most positively that there is anything in the Old or New Testament which would go to show that slavery, when once introduced, ought at all events to be abrogated, or that the master commits any offense in holding slaves. The children of Israel themselves were slaveholders and were not condemned for it. All the patriarchs themselves were slaveholders; Abraham had more than three hundred, Isaac had a "great store" of them; and even the patient and meek Job himself had "a very great household." When the children of Israel conquered the land of Canaan, they made one whole tribe "hewers of wood and drawers of water," and they were at that very time under the special guidance of Jehovah; they were permitted expressly to purchase slaves of the heathen and keep them as an inheritance for their posterity; and even the children of Israel might be enslaved for six years." - Thomas Dew
"My feelings as a Christian points me to my Lord and Savior as a fighter. It points me to the man who once in loneliness, surrounded by a few followers, recognized these Jews for what they were and summoned men to fight against them and who, God's truth! was greatest not as a sufferer but as a fighter. In boundless love as a Christian and as a man I read through the passage which tells us how the Lord at last rose in His might and seized the scourge to drive out of the Temple the brood of vipers and adders. How terrific was His fight for the world against the Jewish poison. To-day, after two thousand years, with deepest emotion I recognize more profoundly than ever before the fact that it was for this that He had to shed His blood upon the Cross. As a Christian I have no duty to allow myself to be cheated, but I have the duty to be a fighter for truth and justice... And if there is anything which could demonstrate that we are acting rightly it is the distress that daily grows. For as a Christian I have also a duty to my own people." - Adolf Hitler, April 12, 1922.
to smaller things. You do know that the president of Zimbabwe, Mugabe, is a Catholic, was invited to Pope John Paul II's beatification ceremony, and is directly responsible for hundreds of documented human rights violations, including the plan of CIBD ("Coercion, Intimidation, Beating, and Displacement" - named by his government
) that won him his 2008 presidential election? The Catholic church not only supports the man, they support his activities by simply not telling him to knock it off.
In the US, the Christian right is colloquially known as the "Gods, Guns, and Get-out" crowd - Jesus and pistols, and they'll start a fight with you if you disagree with them or criticize their position.
Further Christianity is about respecting life. Why do you think Catholics are so focused on teaching that contraception, abortion, and euthanasia are wrong. All of these are classified as intrinsically evil acts because they are against life.
Ah, yes. Of course, they also don't excommunicate Catholics like Mugabe, supported Adolf in his pogrom, and their hirearchy lives in one of the most expensive palaces ever built (the Vatican). They cover up their priests' rape and molestation of children, in many cases going so far as to actively ensure that the priests who were accused of such crimes were moved to new parishes, where they were allowed to continue their actions without real sanction.
They reward fellows like their recent new Cardinal, Dolan, who has actively worked to hide church assets from the victims of church abuse.
Apparently, none of these acts are classified as 'evil', are they?
Look at what Christianity actually teaches with an open mind instead of attempting to draw faulty correlations from human behavior. Unless you are a super genius, you'll have to turn to others to help you learn about it. I suggest turning to some of the great Saints/minds of the past.
We have, believe me.
Catholicism, in particular, is one of the most evil branches of human organization I have ever witnessed, and I say that fully in the knowledge of how hyperbolic that sounds. For all the good the organization does (and they do!), they cannot admit fault, do not live up to their ideals, and actively campaign for their own importance over their mission. They would rather let millions die of AIDS
then have people use condoms. They would rather support dictators (like Mugabe) than excommunicate them for blatant acts against the Catholic tradition and philosophy. They would rather hide malefactors in their own priestly ranks and prevent secular authority from passing judgement for their crimes (while hiding them away in relative comfort) than to stand up and admit wrongdoing or show outrage.
The modern Catholic church doesn't give a damn for anything other than asserting its own superiority.
Oh, and - contraception? /over ninety percent/ of women in the church have used birth control. Control over one's own body is a foundational freedom.
