I don't mean to be patronizing, but that excerpt from the Koran has been analyzed extensively, and has been taken out of context extensively. CLEARLY, it is not what hundreds of millions of Muslims believe or adhere to.
The Bible has incredibly violent sections to it; someone could as easily take phrases out of context from that book to try to marginalize an entire religion.
People need to start thinking proactively on this, and look at what is actually going to solve the problem. It's not declaring that all of Islam is our enemy - which is really exactly what extremists want us to do. They want us to marginalize peaceful Muslims, and have a clear war between Islam and the world. We're playing into their hands by doing that.
Believe it or not, I don't entirely disagree w/ some of Trump's rhetoric from the other day on this (not his campaign rhetoric, but the speech he gave). We all have to identify the true extremists, and work together to eliminate not only those individuals but the causes and reasons for their movement.
