If you want to go back into the past, I am sure you will find all religions has bloody histories.
We are however living in the present.
How many violent (if any) movements that you see dotting the globe today are related to Christianity ?
Finally, you might find these comments I have copied from another side will more than address your questions :
***We keep hearing about these abominable beheadings of unarmed, immobilized, and innocent people. Muslims, apologists for Islam, and much of the Western media scramble, on cue, to assure us that we are not witnessing an established trend that we should worry about. In addition to the fact that they dishonestly euphemistically call the monsters who do this “militants” they also have a hackneyed script which they read from each time another Islamic snuff film is made available on the internet:
Isolated incidents. It seems to me that they’re almost happening on a monthly, if not weekly, basis now. Perpetrated by a tiny minority of extremists. As far as I’m concerned, one is too many, and yeah, I guess extremists is one way to describe these fiends. Not the real Islam. Wrong. Islam’s scripture, literature, and history is horribly bloody from its inception up to yesterday, and the tradition of decapitating ones “enemies” is a long and storied one. I put enemies in quotation marks, because as far as the mujahideen are concerned, anyone who is at all affiliated with the perceived enemies of Islam (in Iraq, Chechnya, Saudi Arabia, Pakistan, etc.) is also an enemy, and subject to the rules of warfare and the treatment of the kuffar(infidels)/mushrikeen(those who put any law equal to or above God’s law). Designations like “civilian” and “noncombatant” are meaningless in Islamic holy war if you find yourself on the wrong side in Muslim lands. I’d also like to remind my readers that countless Muslims fit the bill as recipients of an isolated incident. As Ibn Warraq makes clear in his Why I am Not a Muslim, it is Muslims who suffer first, foremost, and most often under Islam.
These brutal, reprehensible acts of barbarism, while not carried out by all Muslims, are given a silent imprimatur. They are tacitly approved every time a “real” Muslim doesn’t speak out with outrage in protest of such crimes. There just isn’t a mass, coordinated, and universal outcry among Muslims worldwide over this madness. There are prewritten, bloodless public announcements of condemnation which are read and then folded up and put away until the next “isolated incident” requires some apologetics. It’s just damage control. Window dressing for a building on fire.***

ps: timothy mc’veigh didn’t carry out his out his bombing in the name of Christianity, so the example you gave is specious.
