The fact is that Gun Control does not work. Any time new gun control laws are passed, crime rates go up. Whenever gun control laws are repealed, crime rates go down or stay the same. The simple truth is that if guns are outlawed, then only outlaws will have guns. By definition, criminals (the group that gun control laws seem to attempt to disarm (in addition to the general public)), don't follow the law, thus making the gun control laws ineffective on them.

Keep in mind that when the second amendment refers to "a well-regulated militia" it means "a group of citizens formed to defend its community" not "the United States military." This is confirmed by the fact that the second part of the second amendment begins "the right of the people..." not "the right of the military!"
Furthermore, Federal gun control laws are inherently unconstitutional because they violate a state's rights. Remember the Tenth Amendment? The Federal government does not!
Of course, I will not attempt to argue with you gun control advocates who disagree with the facts. Your disregard for reason and factual information is enough of an argument against you. While you cannot help forming an opinion, that does not mean your opinion is right.
