I considered selling my weapons “back” to the government, but after a background check and thorough investigation into the buyer, I determined the buyer has a history of violence and is mentally unstable. Big risk to everyone around it.
This sounds logical enough, but this “government” (the government of the USA) of which this tweeter tweets already possesses an abundance of weaponry. If the US government collected more guns, that would affect those disarmed, but not the US government. The US government would just become a tiny bit more armed.
Gun control laws would likewise make criminals only a bit less armed. But they would utterly disarm the law-abiding. Which would make the law-abiding far less able to defend themselves against crimes of all kinds. These are, and always have been, the real arguments against gun control.
When a joke is felt to be expressing a truth – and if the comments on this tweet that I have read are anything to go by, then this joke definitely is so felt by many – then it becomes important to get serious about the joke.
