The real problem isn't the base religion, what ever it may be. Zealots of any sort, should be shunned as the mad dogs they are. Extremism of any form plays upon the darkest parts of our collective soul. I dont' want to see our species descend futher into that darkness.
The myth of a 'vengeful', 'jealous' God has served the Christian churches down the years as well as the myth of Christ has, to justify just about any monstrous act they care to commit. Look at the Puritans, or the Catholic Church, or the Church of England or... Do I really need to continue?
'Organised' religion really doesnt have a good track record.
The Society of Friends, The Salvation Army and the various flavours of Buddism are the only sects I can can think of who are strongly and blindly pacifist, with the kind of quiet bravery I wish more could show, yet know I would be too weak to have.
Yet, although these are people who band together, united in a common faith, only the Salvation Army can be counted as being truly organised, in the sense of 'organised religion'. There again, they are better organised in an organisational sense than many, having mobile canteens, at the WTC by 10:30ET, and have been operating around the clock since, in addition to those working along side the emergency services.
Just my view....
