The problem is not Christianity. It stems from a dangerous mix of right-wing socio-political movements that have throughout history found a natural constituency in religious fundamentalism. Both are usually reactions to cultural and technological advances (i.e., cyclical religious revivals, like the 'The Great Awakening' of the early 1800s, and the Modern Revival that started in the late 1970s/early 1980s and continues today in this country), and both aim to achieve power over a perceived enemy (e.g., the 'persecution complex' of fundies) justified by a manipulation of ideology and language. There is no tolerance for dissent or questioning as they whip themselves into a group belief that their physical safety and social order is being attacked. Add to that the tendency of those who hold opposing views (usually the normative views of the particular society) to feel intimidated and confused by the irrational behavior in their communities, and retreat rather than confront the revivalists.
The revivalists usually come to power for a time, and then splinter as they begin to identify one another as 'the enemy' (e.g., who is the 'better Christian') after they've vanquished all of the undesirables on their violent powergrab and are left with no one else to fill that void necessary to feed their persecution complex. The cycle ends when they lose power and society accepts the new social and/or technological advances that made folks feel threatened to begin with (e.g., "those lesbians got married and the sky didn't eventally fall, so back to living rationally").
The violence is not due to Christianity - it is due to the irrational group fear that results from religious revivals (ideologically-driven, methodical violence as fight or flight on a society-wide scale, perhaps?).
The good thing is 'this too shall pass' - it always does, I just hope it happens sooner than later in the case of the current violent revival we're in the midst of.

A good read from Katherine Yurica's
'Bloodguilty Churches':
The GOP, joined by a chorus from the religious-right and the neo-conservatives who have sought to advance Mr. Bush’s power have all watched admiringly as he struts across the stage of America’s political theatre. Lassoing and exaggerating the importance of three issues highly susceptible to emotion baiting and a charged current of fear and irrationality, clever men have hijacked the churches into believing they have taken the moral high ground in America.<60>
The churches laud Mr. Bush as a “moral man” simply because he is against any legal union between gays, against any abortion and essentially (for all practical purposes) against stem cell research.
Sadly the churches and Mr. Bush have no knowledge of God. They are completely ignorant that in the Bible, the existence of ten righteous people in one of the cities would have been sufficient to spare Sodom and Gomorrah from destruction,<61> but ten righteous people are insufficient to spare the nation that refuses to defend the rights of the needy!<62> And what is perhaps even more significant, God equates the lying of church leaders—the false prophets of Jeremiah’s day, their adultery, and their encouragement of evil doers to be no different than the sins of those living in Sodom and Gomorrah.<63> The problem with today’s church leaders is that they refuse to confess their own adulterous acts while condemning the most hated and reviled members of American society—like poor Matthew Shepard—heaping vile abuse and death upon others so the eyes of churchgoers are always directed away from themselves, insuring that others will always be the scapegoats.<64>
Roman Catholic Bishops, while urging and even threatening their parishioners to vote only for those candidates who oppose abortion and gay unions, <65> hid active pedophiles from discovery and refuse to subject priests to prosecution for their criminal acts. If that is not enough, the Bishops have removed the churches’ auditing program on known pedophiles.<66> One is forced to ask, which sin is the greater—or which act does the most damage—the pedophiles or the consenting adult gays? <67>
Nor do the protestant churches have any excuse; they are shepherds over flocks living in the Bible belt where the towns, counties and states have the largest number of divorces in the nation. While Jesus was silent about homosexuals, he was not silent about divorce. He called divorce a sin unless adultery was the reason for it.<68>
According to columnist Andrew Sullivan, “the states with the highest divorce rates in the U.S. are Alabama, Arkansas, Arizona, Florida, Georgia, Mississippi, North Carolina, Oklahoma, South Carolina and Texas,” which just happen to make up so-called “red” states which overwhelmingly support George W. Bush.<69> On the other hand, the states “with the lowest divorce rates are: Connecticut, Massachusetts, Maine, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island and Vermont.” Sullivan points out, “Every single one of the low divorce rate states went for Kerry. The Bible Belt divorce rate…is roughly 50 percent higher than the national average.”<70>
Sullivan says, “A staggering 23 percent of married born-agains have been divorced twice or more.”<71> And who has the most teen births? In the state where preaching against teen sex is the strongest—teen pregnancies are the highest: Sullivan says, 16.1 percent of all births are teen births in Texas, but in liberal Massachusetts, “it’s 7.4 almost half.”<72>
How dare the churchgoers think of themselves as a moral army, preparing America for their rule! Yet they protect pastors accused of adultery and homosexuality,<73> while they condemn without mercy “humanists” and “liberals” in America who follow the teachings of Jesus and seek to protect and provide for the poor and do justice.
There's a grave discrepancy between what the Bible says and what the churches are doing: the Bible makes it clear that Christians can associate with anyone who lives in this world. And what is even more significant, a Christian may not judge non-Christians! Even if Christians are the majority, they may not make laws that deny civil liberties to people because of alleged sexual sins. St. Paul makes it clear: a Christian's area of influence in such matters is restricted to the confines of church membership where members must expel an immoral offender from their midst: slanderers, liars, deceivers, the fearful and those involved in adultery or pedophilia comes to mind. Those members may not keep their church membership (1 Corinthians 5 : 9-13). The churches in America, however, have it just the opposite: they point their accusatory fingers at everyone outside their churches, and they seek to deny non-members civil rights, but never even look at their own hearts and guilty souls.
