Death wishes are serious business. At the risk of someone invoking Godwin's Law, I will mention how channeling hatred against certain groups gave rise to the Nazi (National Socialist) party in Germany around 90 years ago.
At the risk of someone (you) invoking Godwin's Law, would you say the Jews of Germany, Poland, Hungary, etc. and people sympathetic to their cause -- not getting killed by the government -- would have been wrong to wish Hitler, Himmler or Goebbels dead because all three had loved ones -- Hitler a girlfriend (OK, a wife for a couple of hours) and the other two wives and children?
Would a simple "Go to hell, Limbaugh" pass muster today, or is that still too insensitive, given that, as far as I know, all religions that include in their beliefs the existence of hell require that one die before entering any eternal abode?
