First, anyone who takes the trouble to actually read the scriptures of a religion to understand what it teaches is ahead of too many others who don't take the trouble.
But balance is needed is to not focus on only some passages but read those that have the opposite message. I can find passages of both peaceful and warlike kind in Islam. I can find very positive and loving messages in strong Hadith.
Also, it's important what people who follow a religion actually do. When Buddhists use violence to attack Muslims, they betray their beliefs. When Christians do the opposite of what is in the Sermon on the Mount, they betray their beliefs. And this is true of Islam as well.
I understand that this is a tangent, but you opened the door...
BECAUSE Muslims claim that their scripture is PERFECT, it is not good enough that *some* passages are peaceful. Muslims continue to CHOOSE to raise the bar and demand that we agree that their scripture is perfect. They make it hard on themselves.
