I do. I believe there is evil in the world, and evil people out there doing evil. Many people do not believe in the existence of evil.. Scratch a multi cultural liberal, and you will find someone who believes that all people are good, and evil doers are simply misinformed. Or misunderstood.
Me, I believe that evil exists, and that it is good to oppose evil. The most effective opposition comes from the use of firearms. Certainly in the United States, the availability of firearms deters a lot of crime. The would be robber has to worry about the storekeeper with a handgun in the cash drawer. The would be house breaker has to worry about the homeowner with a shotgun. The would be carjacker has to worry about a piece in the glove compartment. And even the American police are usually quite polite, partly because they know the citizen they offend might be armed, and might do something about it.
And so, I believe in the private ownership of firearms. And I want my firearms to be as deadly as possible, within certain limits. Once firearms are displayed, I want to win the ensuing gunfight. The biggest limit is the prohibition on private ownership of machine guns. This was made law back in Al Capone's time. It seems reasonable, and the law is still on the books and still enforced.
The AR-15 (and lookalikes from SIG Saur and others) has been Army issue since the Viet Nam war. Most guys were trained on this rifle in the service. After they leave the service and go out to buy a deer rifle, they often choose the AR-15 'cause they are familiar with it. It's enough gun for deer, it doesn't kick much. Ammunition is cheap and widely available. There are a LOT of them out there, and taking them away from that many owners would be VERY difficult indeed.
The current Democratic push for more gun control (more ways to take citizen's guns away) leaves me cold. Ordinary citizens ought to have a gun around the house, just in case ISIS come calling, or the house breakers turn up.
