So let me get this straight. Because a weapon can kill, you should be able to cuss as you wish, regardless of audience.A site that sells weapons for killing,but limits a man as to what he can say......
Most if not all here have our weapons in the hopes that having the means to defend ourselves, will prevent us from having to kill someone.
If we do have to kill then it will be our last resort or for a greater purpose, as I don't know a sane man that enjoys the act.
Unless you are referring to hunting, in that case your rationalization would just be juvenile.
