Until everyone here complaining has the balls to step out there and have a 90 mph fastball coming straight at you, without a glove to catch it, and still make a call in a split second, then you can complain. Until then, shut your mouth. The umpire isn't going to change his call because you are yelling that he's blind or whatever name you can come up with. If anything, he'll keep calling the same thing.
I know that when I was umpiring baseball games, me and the catcher would laugh at the fans who were yelling about every single pitch. And this was when the fans are about 15 feet away. Lord only knows what the umpire is saying about the fans when he's about 50 feet away at the Tigue.
