“If you compare the pro-gun activity in the blogosphere versus the pro-gun-control activity, the scales have just tipped tremendously in their favor,” says Josh Sugarmann, founder of the Violence Policy Center in Washington, which advocates for more gun control in the US. “There’s much more engagement, more involvement, and they clearly have more free time than people on our side of the issue do.”
Well, Josh... It's not that they have more free time than your side. The reason there is more engagement and involvement on the pro-gun side is because it's personal. The vast majority of pro-gun bloggers are defending their hobbies, careers, ways of life, means of safety, and most importantly their rights. That is something that stirs ones passions and soul and makes them want to get involved and go that extra mile.
On the other hand, your side isn't more engaged and involved because your fight is an impersonal one. Aside from certain individuals who have a personal vendetta against firearms, the average gun control advocate is nothing more than a hired gun or self-righteous busy-body trying to sell a failed political position.
And that is ultimately why the pro-gun side can attract so many engaged and involved people. That is why the NRA can fill a convention center for an entire weekend while you would be lucky to fill a Chuck-E-Cheese for an hour.
