When the Catholic Church tried to cover up the molestation of children many Catholics quit in disgust, yet nothing similar appears to be happening in Islam. Christians are being slaughtered by Muslims in Africa, for example, and there have been no Muslims marching in the streets asking that it be stopped.
Yes, innocent and law abiding citizens should not be vilified for their faith, unless that 'faith' is subjugating and oppressing human rights and freedoms and the bodies start piling up. Sometimes 'faith' is overrated and beliefs simply nonsense. We all know that.
People must expect to be responsible for their beliefs, and what group they belong to, or expect criticism. This is just the way it works in the adult world and Muslims should either be prepared for it, or do something positive about it. But playing the victim card when it is members of their faith creating international terrorism is not a ploy that can continue indefinitely.
