Wrong again. The main purpose of an AR15 is dependent on the intentions of the user....just as a hammer is. When the intentions are to save a life, an AR15 is an exponentially better choice. When the intention is to kill....well, the statistics demonstrate more lives are killed with a hammer than a rifle, and exponentially more lives killed than those killed by an AR15 specifically
However, if the intention is to drive a nail thru some wood, the hammer is an exponenially better choice.....than pretty much, any rifle, including an AR15
That's how analogies work......making concepts simple to understand. Especially those concepts that are pretty simple, and fully supported by facts and statistics to begin with
