I agree, but how much does it actually help? It's an unscientific poll, so it doesn't mean that 92% of people are against the proposed gun control laws. Heck, it doesn't even mean that a majority of people are against those laws. All it means is that a lot more gun-rights supporters happened to visit the site and vote, probably mostly due to threads like these.
The average gun-rights supporter tends be more involved than the average gun-control supporter: For many of us, guns aren't just a political position, they're a passion and a way of life. Therefore it's easier to get us to vote in online polls, just like the OP got us to vote. And that's why these unscientific polls tend to lean our way so often. But that doesn't mean they reflect the general public's views at large.
But like I said, it sure can't hurt; and if even one middle-of-the-road person reconsiders their stance after seeing the 92% ratio, then we've helped accomplish something.
