My primary point is the separation of church and state that is traditional and accepted by Christianity makes even the errors of its adherents less harmful than those of Islam.
Second, when discussing religion, language changes. We all seem to accept that the exact opposite of the truth is the greatest form of “TRUTH” when discussing religion. For example,
“Jesus Christ is the perfect man and worthy of emulation.” can be accepted by a religious Christian in a religious setting. When it is pointed out the Jesus Christ was not documented as having a job, never married, didn’t have any children, his value as a role model diminishes for those of us who have steady jobs, marriage and children, but religious Christians have difficulty with statements that his value as a role model is diminished. Christians just don’t apply bad examples to their every day life, in part due to our habit of separation of church and state. That habit built on the Jewish domination by Rome, and the European reformation where state churches often had to come to terms with many people in their country that were dissenters.
By contrast Mohammed is held by Islamists as a role model, and his example as a married (with multiple wives) man with children, his occupation as a successful caravan raider is pointed out. His example of having murdered the local Jews after the battle of the ditch is considered as a good example for what to do after resistance stops, not just to the enemy, but to those insufficiently enthusiastic. That murder of innocents is their guide for what they would do after they took over Israel, or Detroit.
As such though I as a matter of conscience do not hold to either faith, I find the Muslim faith significantly more harmful.
