USPSA is a competitive discipline. Theoretically, it has an interest in establishing and then regulating its rules and divisions to ensure that actual, substantial competition is happening.
Contrary to what you have expressed, if you have a division that has ceased to be competitive (or never was), then it does cheapen the sport. This is not church-league softball.
It's entirely reasonable to have a conversation about how to handle a division that only has 26 shooters at it's national championship. It has nothing to do with a desire to "fuck with" anyone else.
It's also entirely reasonable to have a conversation about a division whose defining feature is to be redundant to the most popular division. The most popular division already being adjustable (by rule) to fit mag cap requirements according to state law.
PCC is a different animal. I haven't met any reasonable person who says USPSA should divest itself from PCC. I think it's clear that the demand is there, and it's a very competitive division. However, it's entirely reasonable to discuss the effects PCC has on matches and to consider all options on how to best integrate it into the sport.
No one wants Joe C-class gone from the sport. But on big-picture matters of competition, maybe it's time we stop catering to the lowest common denominator.
Explain to me how 26 shooters "cheapen the sport" by competing in a Division ALL BY THEMSELVES at a Nationals.
Secondly, USPSA IS a Sunday afternoon church softball league if you compare the M/GM contingent against everyone else from D to A class that either:
* One, do not have the drive and desire to crack into M/GM
* Two: do not have the time or financial assets required to crack into M/GM
* Three: shoot the sport for fun and don't give two fucks about the 10% of the membership with GM cards.
Should we limit golf club memberships to single digit handicap golfers because those with double digit handicaps "cheapen the game?"
You're approach is exactly what is wrong with IPSC in general and USPSA in particular. It's a game played on the weekend by guys who love to shoot but may NEVER be TGO. No different than drag racing where there are only 3 Pro Divisions of competition but the overwhelming bulk of the cars in the pits and staging lanes are "sportsman" cars who by their entry fees support the sanctioning body and local track.
Playing to the lowest common denominator isn't an option, its a necessity. Otherwise USPSA would have 250 like minded members who think maintaining divisions people participate in, regardless of the numbers at a national basis, is a waste of time and effort along with being below them.
For the life of me, I can't figure out why L-10, Revo, and PCC cause people to froth at the mouth when whatever goes on in those Divisions doesn't effect them in the slightest.
