A lot of people enjoy going out and doing verbal battle on the intertubes with people who hold diametrically-opposing views. For example, if it weren't for all the gun rights activists showing up to argue in the comments section, your average gun control blog would only be read by the author and his mom; it's almost like they're written solely out of masochism.
In these arguments, reams of statistics and the outcomes of all manner of surveys get lobbed back and forth, which is one of the reasons I never participate, and rarely even go read. See, I don't really care about the statistics or the efficacy (or lack thereof) of gun control laws. My right to own a gun (or anything else, for that matter) is not contingent on what other people do with that right. It wouldn't matter if everybody else on the planet misused their firearms every day, that doesn't have a thing to do with me or mine; group punishment doesn't belong outside of prison, basic training, or Mrs. Krabapple's third grade classroom.
Rights belong to individuals, not groups: Just because all the other kids jump off the bridge, it doesn't mean you can push me off, too.
