Oh yeah I love apples to oranges comparisons too!
Street gangs-avoid unsavory inner-city areas and chances are slim that you will be gunned down in street gang violence.
Muslims-chances are also slim that you will be killed by an islamic terrorist but unfortunatley they seem to have a penchant for targeting areas/activities that it isnt always easy for the average person to avoid-public/mass transportation, large gatherings of people such as shopping centers and religious services.
Street gangs-unless you are a member of a rival gang -random acts of violence
Muslims-plan and execute acts of violence based on the maxiumum amount of casualties they can inflict, although incidents like the Fort Hood shooting and the dirt bag gunning down airmen in germany seem to be random acts. But who knows for sure?
