I am neutral / undecided on the gun ownership issue but simplifying and using misleading information doesn’t help anyone.
Switzerland also has a lot more social security than the US. I agree that it's more complex than "guns are bad", but using Switzerland as an argument for gun ownership is just glossing over the details to come up with an artificial example where gun ownership doesn't result in increased violence.
Though I do not concede the use of the word "artificial" as correct in your sentence, bringing in the Swiss data point is incredibly relevant in response to a claim that "Actually, no, study after study shows that the amount of guns in a society is strongly correlated to its homicide rate, both directly as well as indirectly."
