Your kidding?
No player should curse at umpire, all do. To call 2 outs anytime in the game is the umpire becoming bigger then the game. ASA/USA umpires seemed to think they were when I was involved. They caused nothing but trouble for themselves and ruined the game. Good umpires had players respect and if a player cursed after a call let him say his piece and moved on. Players respect that and just say it and move on. Keep complaining, sure get tossed
