>"First, the gun problem is pretty much specific to the US"
The 2A is not a "problem", nor is good people owning/carrying guns. There are problems with violence, both with and without guns, and that is not "specific to the USA". There are also problems with enforcement and follow-through for existing gun laws. Worrying about 3D printers is ridiculous. But so are many other types of "gun control" like so-called "gun-free zones."
>"Second, in a country which just this year has had 21 school shootings as of today,"
"School shootings" is a semantically-overloaded term. Most are not in the school, but on property around the school. Usually those shot are also not related to the schools and often not even during school hours. I am not saying it isn't a problem, but the data are often twisted to make it sound far worse than it is. And that is the case with the article you cited. They hide the ACTUAL data, like category of who was shot, when, exactly where (inside, outside, field, woods, parking lot), and full circumstances. Their data INCLUDES self-defense use, for example. It INCLUDES non-school gang-related activity. It INCLUDES at night or non-operating hours. It INCLUDES a public sidewalk or edge of the woods, or parking area far away from any building.
>"the real problem isn't printed guns. It's a whole set of cultural, social, political, and governance flaws which need to be fixed"
Agreed.
>"Citizens of other nations don't feel a moment of panic and start scoping out shelter and escape routes when they hear some random loud bang while walking down the street."
Neither do perhaps 99%+ of Americans. The vast majority of the gun crime is focused in small geographical spots in the USA.
>"Yet ironically, the "land of the free" is now a Fascist dictatorship"
That is, of course, nonsense.
>"Leave the 3D printers alone"
Agreed.
