That's simply not the case, obviously. Some people object to the "unfair advantage" one has when wielding a gun against an unarmed opponent, but that advantage applies to all weapons.
*Shrug* I simply don't know what people are hoping to solve by getting rid of guns. The use of guns are a symptom, not a cause. Humans are fragile creatures, banning guns simply means that people will kill each other with different means.
