I've seen the above imaged shared and liked on Facebook many times now and I really like this one because of one word. Disciplined.
Any idiot can have a gun. Sadly, far too many do. While the ability to arm yourself is your right, that right comes with a huge responsibility. Discipline.
If you choose to exercise your right to bear arms, don't just buy a gun and stick it in a closet or nightstand drawer to be used if needed. Practice with it often. Know it inside and out. Store it safely. Carry it safely. Use it correctly.
Being a responsible firearms owner will help defeat the gun control arguments, and defend your right to bear arms.
