We all have our own travel hang ups, but you may be limiting yourself based on American biases. According to the UN National Statistics on Crime and Criminal Justice, the US and Argentina have similar homicide rates, the US has a tremendously higher rate of assault and major assault versus Argentina, and the US has a much higher rate of rape than Argentina. Argentina does have a higher incidence of robberies, but things can be replaced. Humans cannot.
To each his or her own, of course. But it always pays to do a bit of research on the places we are visiting.
