Know Your Topic.

If you're going to advocate some controversial position you should know a great deal on the subject. Not doing so will get you in trouble. While trying to look up a pistol manufacturer on Google I stumbled across a pro-gun control blog called Gun Guys. Skimming through it I came across this piece about a young woman suing the careless hunter who shot her. The young woman was hit by a 7mm Magnum slug. That fact resulted in the following comment: He was shooting at a deer with a 7mm rifle? Did he expect there to be any of it left afterwards?

Apparently the writer didn't bother to do any research. The 7mm calibre is a common size for hunting deer. It's in roughly the same size range as the .30 calibre rounds that have long been a standard hunting calibre. The clown in question no doubt expected to find the majority of the deer to be where it fell after he shot it. All that making a statement like that does is allow one's opponents to point to it as an example of your general ignorance on the subject, and hence that your ideas shouldn't be taken seriously. And if there's anything that gun control foes are going to jump on it's anything that indicates an ignorance of firearms.
