I just get a bit disenfranchised arguing on this site because as a general note, if people believe hard enough that they're right, than no amount of logic and evidence against can prevail. And I don't have all the answers, Hell, I probably assert my views too much. Though it's usually those who do pretend to have all the answers that can't be convinced otherwise.
Frankly, this site is of such better quality than other forums I frequent, it operates on a whole different level than your average forum.
The reasons for it are this...
1. We tend to run out idiots right quick, our mods can be restrictive, and downright authoritarian at times, but it's ultimately a necessary evil. Also, being a mod is probably the most thankless job in the world, and I hate to think what these forums would be if the admins didn't run as tight a ship.
2. Fanboys and their various behaviors are looked down upon. Sure, as a community, we seem to have more hatedoms than fandoms; on almost any given day there will be posts bashing Twilight, the Inheritance Cycle, or some other garbage that belongs on Fanfiction.net. People who are fans of stuff argue constructively here rather than the usual excrement-flinging howler monkeys that you see on less respectable sites.
