The artist apparently has no connection with relevant facts. The 30K deaths by gun fire (ignoring his badly phrased “gun deaths per year” which to me means that many guns die each year) includes suicides, justified homicide, and praiseworthy homicide. Furthermore there is no evidence that fewer restrictions results in more criminal homicide or suicide.
He also fails to acknowledge the human rights issues involved.
But then, bigots don’t care about facts anyway.
