While the idea of chipping away at gun control, in the same manner as the antis have chipped away at the RKBA, is a fine one - and one that I endorse because we're never going to see an overnight end to the infringement of our RKBA - this particular argument is misguided. No offense, but that's my opinion.
ANY argument that our RKBA depends on something as trivial as sport weakens the 2nd Amendment and weakens our cause. Sports can be regulated to death or just outright made illegal - and there goes any argument for having guns based on that sport. This is exactly how the English people lost their RKBA in the late 1600's, and how many have lost their rights ever since. The whole CONCEPT of "sporting use" that was introduced into American law with the 1968 GCA is an alien one - we can thank Sen. Thomas Dodd (father of today's ultra-lefty anti-gun Sen. Chris Dodd) for lifting that particularly odious concept from the 1938 Nazi Weapons law and bringing it to our shores.
As proponents of the RKBA, we should understand this and communicate it to the rest of society. The Founding Fathers were not interested in trivial things like sport. They had just fought what was, in essence, a civil war against the most powerful ruler on the planet less than a decade before the BOR was ratified. The Constitution itself was the foundation document of a society and a government that they hoped would last indefinitely, bring freedom to millions for generations to come here and serve as a beacon of hope and an example to the rest of the world. Yet, somehow or other, the idiotic notion became implanted in our national psyche that the 2nd Amendment was stuck in the middle of the most important document in our nation's history by men of great intellect and seriousness, in order to preserve some beer-bellied, tobacco-chewing, in-bred redneck's "right" to hunt deer in the 21st century. Sorry, that's not right. The 2nd is about POWER, specifically the power of the People to deter the imposition of a tyranny by our government or, if that doesn't work, then to make sure that we have the tools with which to push the Constitutional Reset Button, thereby getting rid of the bastiches and starting over.
Please don't let the other side - the enemies of personal freedom - set the terms of the debate. Doing so is a certain recipe for disaster and loss. WE should tell them that the Founding Fathers set the terms, and they don't include sport. Let them know that the RKBA is about FREEDOM, about limiting the power of government, NOT sport. Let them rage, like Fat Ted Kennedy (Drunken Murderer, MA) did at Ashcroft's nomination hearings, but let them know. After a while, they'll understand not to mess with us or our guns.
Screw chipping away at "sporting use." Let's get that odious Nazi idea out of our law by repealing it.
