Since you wanted to make a case that Islam is violent, let's put it in perspective with some facts.
In the current Mexican drug war, more than 60,00 have been killed, with more than 5,000 more missing. Most of this has happened in Mexico, but CNN reported that there were several related killings in Alabama, Texas, and Georgia. Pretty close to home.
Meanwhile, the absolute highest number that I could find was 11,267 deaths at the hands of Muslims extremists - worldwide for 2012. This was from the Blaze, so I figure that you might accept that. Every other report quotes MUCH lower numbers.
Religion (Islamic or other) doesn't seem to tip the scales to one over the other. The desire for more money and power seem to have a lot of influence on people's actions though.
As for the number of terrorist that commit attacks being predominately Muslim, the FBI says "not so". You might need to look out for Jewish terrorists more than Muslims.

Now, to be perfectly clear, I am not stating that "Islam is a religion of peace". I don't want you to try to put words in my mouth.
