I respect your opinion, and from where you are from, what you are saying is both logical and factual. BUT. The US isn't Denmark. The underlying difference is the US has so many guns, that you're not going to get rid of them without some massive dictatorship like crackdown. To propose getting rid of guns in the US is just as ridiculous as thinking we'd be able to deport tens of millions of illegal immigrants easily.
Denmark doesn't have as many wide swaths of sparsely populated towns, it's a fact. Population density for Denmark? 131/km2. US? 34.2/km2. Last but not least, Denmark has a different cultural history than the US. The gun is a simple of freedom and liberty. It's an enshrined notion in our society. The ability of the people to be armed curbs oppressive governance.
So please, respectfully, take your elitist attitude elsewhere. No one here gives two shits whether you think we're "silly."
