Am I Wrong to get upset because i get killed by launcher type weapons?

What annoys me most if when people kills others with launcher type weapons. I know that there are challenges to "kill or destroy killstreaks" or somjething of that nature, and i usually ask if they were doing said challenges. I really really believe that even though the weapon is there, there is absoultely NO reason to use a launcher on a human person. Guns does enough damage as it is.

Am i wrong to be upset because people kill with launchers? am i the only one?

Id like to hear some opinions.
