All ball fouls can be a bit ridiculous, too.
I've seen a player lose an innning because his bowtie fell off and hit an object ball. I've also seen a player lose an inning when one of his cufflinks came off and landed on an object ball.
I don't think this is about being a purist at all. Penalizing reversible pre-shot events that are clearly recognized as having no bearing on the upcoming shot's outcome, in my view, adds a random element to the results that can and should be avoided.
An example from golf is when a player tees up the golf ball and accidentally knocks it off, leaving it inches from its starting position, before intending to play the shot. Even in competition, he/she is permitted to place it back on the tee without penalty. Perhaps a purist would say that knocking the ball off the tee is a shot, but the rule makes sense.
I'm fine with all ball fouls for balls moved during the execution of a shot, but don't think pre-shot infractions should be similarly penalized.
I agree with Stu here. It doesn't have to be all or nothing.
Pre-shot touching doesn't necessarily interfere with the play of the game. Balls can be replaced to as close to their original spots as possible at the opponents discretion when a ball is moved prior to a person approaching the ball. Yes...it may change slightly...but you do the best you can. Just as if the wind moves a golf ball on the green...the player isn't penalized...they simply replace the ball where they think it was.
And I can guarantee you that my hair has never moved a ball...LOL. So if a strand grazes a ball...that should be a foul? What if a loose hair on my shirt falls off and lands on the ball? Should I be penalized then?
I agree that if a player moves a ball accidentally during a shot...then it can be considered a foul. That would help avoid arguments about whether or not a moving ball crossed the line, etc, etc.
