Re: "Now let's just discuss the deaths caused by people with guns, whether intentional, accidental, or suicidal"

Okay.  According to the CDC in 2010 there were 63000 firearm deaths in all categories (intentional, accidental, suicide, and unknown), 64153 in 2011 and 66724 in 2014. During the same period, background checks on firearm sales went from about 15 million in 2010 to 22 million in 2014. So while firearm deaths increased by 6% from 2010 to 2014, firearm sales increased by 47% during the same period and if the two events were correlated as you claim, the firearm incidents should have also increased by 47%.
