I think where it came from is Steven Colbert had some monologue were he ignorantly said he wanted it to be like voting and rattled off stuff like he wanted them to to be 21 years old, that isn't true for voting. So i think this idiot parroted that without any clue how much more is required to get a gun. Like not being a felon. That's true for voting in most places, but they don't do a background check for voter registration.
