Sadly, as is the case every single time, the citizens who support giving up their right to self-defense miss the bigger picture. When law-abiding citizens turn in their guns, only the government — and criminals — have guns.
The irony here is so glaringly ridiculous that it almost hurts. With the exception of the neoconservative tyrant class, most of the people calling for Americans to be disarmed are not supportive of the current administration. Arguably, many of the people calling for Americans to be disarmed are also the ones taking a stand against racist police tactics and brutality.
The disconnect happens here. People who dislike Donald Trump and who, rightfully so, call out the problem of police brutality in America, want to give all the guns in the country to Donald Trump and the police.
The bottom line is that government, historically speaking, is the most violent entity in the world. In the 20th Century alone, governments were responsible for 260,000,000 deaths worldwide. That number is greater than all deaths from illicit drug use, STD's, Homicides, and Traffic Accidents — combined. And this is who we want to have all the guns?
