It isn't actually.  There's a wealth of data to link ready availability of guns not only with mass shootings but also with murder and suicide rates.  It takes an intentional blindness to facts to believe that the gun ownership rate in this country doesn't contribute to the rate of gun deaths.  The commitment of some people in this country to gun ownership leads directly to the children murdered at Sandy Hook and in Texas.  

Same question to you as to the OP.  Do you choose dead babies or your guns?
