I'm not one of them myself, but I know people who would argue that the ubiquity of sugary foods in our diets is a bigger net negative to society than guns.
I don't totally disagree, but you have to go a little further to really make the point. excess sugar seems to cause more deaths than guns, but how many years does it take off of people's lifespan? a poor diet killing someone at 65 instead of 78 is not quite as bad as a healthy 20yo being shot dead in an instant. to go even further, what's the cumulative impact to quality of life, even if one does live to a ripe old age?
