I'll play the other side of the coin:
Maybe part of the problem apparent here is the number of people that think league bowling is the PBA tour and take it way too seriously.
Russell, lumping all 'league bowling' in one bucket is too simplistic. Just like there are many different kinds of cars, there are different kinds of leagues: Seniors, Mixed Handicap, Classic Handicap and Scratch. Each has it's own written (and unwritten) rules regarding what's acceptable behavior.
The behavior of the self appointed fool in Shipper's league wouldn't be accepted in many settings. We've tossed guys before the end of the season for similar repeated antics. It's not a question of taking things too seriously. Rude is rude, and for many this guy is over the top.
Given the situation, it just sounds like Shipper will have to find a bowling home elsewhere. Sometimes that's the only answer.
