As iCowden says, the US does not even make the top 10 in the homicide by gun list by country.
So, that means that the US is a safer country despite the huge gun ownership.
Saying that the US is safer than troubled, violent and much less prosperous countries like Venezuela, El Salvador, Guatemala, Honduras, Colombia etc. does not exactly fill me with confidence about its attitude to gun ownership, or your use of statistics.
Most of the countries on the top of the list are devilled by problems with organised drug crime and gangs and a more valid comparison would be with relatively stable, wealthy countries.
You seem happy to cherry-pick not particularly relevant statistics that you think strengthen your arguments at the same time ignoring the clear statistics that show the US in a bad light compared to comparable countries
