No one is advocating taking away your guns. What most people want is a better control on who owns them and the power of some guns. Better background checks, banning people on no-fly lists and stopping sales to mostly anyone at gun shows.
A firearm is for the purpose of killing and the more powerful the more people they can kill, the more a person has the more he can kill. We know that from incidents like Sandy Hook, Columbine, Orlando, etc.
