Where are the anti-gun folks?

Eric Zorn of the Chicago Tribune asks that very question:

[E]ach timeit has struck me how tiny, uninspired and vague the response has been from those who favor new laws to try to keep guns out of the hand of evildoers.
While the gun-rights folks weigh in quickly and forcefully with links to studies and detailed arguments, the gun-ban folks are mostly quiet.

Zorn’s comments illustrate the amazing effects of the internet on such issues.
In the past, it took some time for responses to be published; waiting for the next edition of a magazine or newspaper often took weeks, and then only a limited number (if any) of replies were published. There was no way to direct feedback to the author, only to the editor’s desk, who may or may not forward the comments to the author. Many people received news from local newspapers, a few national/international papers, and the radio/TV news programs by major networks (CNN, ABC, CBS, etc.).
It was difficult and expensive for large networks of people to organize and communicate, so there wasn’t much large-scale organization for pro-gun viewpoints other than the NRA, which was only moderately responsive. Organizations with impressive-sounding names could posture and appear to be more influential than they actually were.
These days, the internet makes it incredibly easy to publish information, link to other sources, and spread news around (for example, Zorn’s column was made known to me by means of Rustmeister’s Alehouse, who published his posting about 8 hours ago — hat tip to Sebastian who made me aware of Rustmeister’s posting). Message boards like The High Road make it easy to communicate with other like-minded individuals around the world instantly.
These days, it’s quite clear that the “pro-gun” viewpoint is really a grassroots one…there are hundreds (thousands?) of independent bloggers, large message boards, communities, and online vendors dedicated entirely to talking about guns, selling gun parts and accessories, and so on. Word gets around the gun community incredibly fast (see the Zumbo Affair, where a deluge of phone calls, emails, and other communications resulted in Zumbo losing his column and sponsors before the NRA knew about it, let alone published a press release), with often influential results.
Let’s keep up the good work and use this influential communications medium to better effect.
