The Law of Fan Jackassery

The amount of jackassery in a fandom is a function of the fandom's obscurity.

This means that the proportion of jackasses to normal people sharply increases with the obscurity of the fandom until it reaches a peak, then sharply drops off again.

For fandoms not too far from the mainstream, the fanbase is larger, and therefore its native level of jackassery becomes more representative of the level of jackassery in the population at large. Jackassery is discouraged because the community is large enough to drown out the voices of individual jackasses.

As you move away from the mainstream, fandom becomes more geeky, composed of people who are, at best, less normal, and often, less sane.

However, beyond a certain level of obscurity, the size of the fandom drops to a point where it can no longer support an elevated level of jackassery: if the whole fan community consists of six guys, they just stop hanging out with the guy who's a giant jerk. Thus, for example, fans of VR.5 are a really nice bunch of people. Both of them.

Peak jackassery occurs when obscurity is sufficient that acting like a normal human being is no longer expected of the fans, but the fan community remains too large and diverse to make a unified stand against the jackasses. See also: Fan Dumb, Misaimed Fandom.
