Let me give you a little logic help here: To assert something caused this you need to point to something that 1) did not exist in 2014; 2) did exist in 2016; 3) can plausibly cause a rise in gun fatalities.
You need a check on all of these. Note: comments about my screen name are not on the list.
Your "ZMFOG!! because the NRA" argument does not survive #1.
What passes for logic in your monosynaptic cranium doesn't stand the sniff test in the real world. Just your #1 is risible. Ever heard of propagation delay? However, in 2014, the gun loons continued to ease gun legislation, particularly with the really dumb idea of allowing guns in bars and university campuses. The damage was already in flight, though...well before 2014.
Waving your hands about more frantically does not constitute a better argument.
So, as best you can, describe exactly the NRA did between 2014 and 2016 to cause this increase. Support it as best you can with facts.


Btw, why can't some of you men disagree without attacking each other?
