I have been around guns since age 3.... learned not to even shuffle my feet holding one before breaking it down to ensure it was not loaded [even if I had just done so 2 minutes before]  I used to have guns* and support the second amendment......  but   the average person does not NEED an AR-15  or anything even close for self defense or home defense.  Those weapons were designed for military assaults,  not home defense.   -----  a major part of the gun problem in this country is that there are too many gun enthusiasts who feel that using the term magazines over the term clips means they are an expert and makes valid anything  else they choose to say or do.
*  I have ET and in my 50s the severity of my tremor got to the point that it would not be safe for anyone, anywhere if I held a loaded gun . I consider myself a reasonable person, so I gave up shooting.
