Your argument is invalid, since the dogma for Christianity is different than Islam. Religious fanatics abound in both of these sister religions. You only have to read the news to find Christians threatening death and murdering doctors, as well as Muslims threatening and killing over their dogma.
So you are saying one's dogma justifies their behavior? You just confirmed my point. Their "dogma" justifies, mass murder, suicide bombings, killing of innocents, honor killing, sexual mutilation, stoning, physical mutilation and a host of other barbaric acts. Their "dogma" IS the problem!
Furthermore Christian fanatics will sometimes kill abortion doctors. Muslim fanatics will sometimes kill cartoonists. Are you making a moral equivalency?
Below is a link that will lead you too, among other things, a list of 40 or so acts of violence perpetrated in the name of Islam since 2003 (compiled by the U.S. state dept). Thousands of people killed in the name of Islamic "dogma". Please provide me with a corresponding list for Christian fanatics.
