Unfortunately, most moderate muslims have not read the Qur’an thoroughly. Please make sure you know what the Qur’an actually says:
Because of that, We decreed upon the Children of Israel that whoever kills a soul unless for a soul or for corruption [done] in the land – it is as if he had slain mankind entirely. And whoever saves one – it is as if he had saved mankind entirely. And our messengers had certainly come to them with clear proofs. Then indeed many of them, [even] after that, throughout the land, were transgressors.
Indeed, the penalty for those who wage war against Allah and His Messenger and strive upon earth [to cause] corruption is none but that they be killed or crucified or that their hands and feet be cut off from opposite sides or that they be exiled from the land. That is for them a disgrace in this world; and for them in the Hereafter is a great punishment,
“We decreed upon the Children of Israel” means that particular passage relating to peace does not apply to muslims. The muslims themselves are instructed by verse 33. Therefore, Islam is not a religion of peace.
It sanctions murder, crucifixion and the dismemberment of anyone opposed to Allah and Mohammad. Because civilian populations pay taxes, they are seen to be supporting military action against Islam. Therefore, jihadists believe that civilian populations are fair targets. This is why fervent muslims who have actually read the Qur’an properly go out to commit jihad.
