Guns are inanimate objects, incapable it doing anything on their own. That is a fact. It cannot be questioned. All firearms, which are tools, are designed to do one thing and one thing only, expel a projectile, or projectiles, down a tube, using the pressure of expanding gasses from fast burning powder. What that projectile, or projectiles, are used for, good or evil, is an individual choice.
People are killed by products that are advertised by the NFL almost on a daily basis. The NFL, the general population, are not concerned with that, nor should they be. An organization, etc, that advertises legal products, is in no way responsible if those products are used to commit a crime.
There is a story today, in the local news, about a woman that was run over by a car the driver fled the scene. It is conceivable that the car in question was advertised by the NFL. What is the difference? Are those killed in a car crime somehow more dead than those killed in a criminal act with a gun?
As I said, I don't care what they do. It's their choice. It's just fun to discuss this.
