What I don't agree with is INTENTIONALLY TRYING TO HIT THE PITCHER. That sadly has happened to me a few times and it usually pisses me off. If I am standing in the middle, haven't moved to show that I am trying to take away the hole and you SAY you are coming at me (yes, that has happened) and then try to blow me up, that is TOTAL BS. Now add to that using a shaved stick, that is where I see it being a POSSIBLE legal matter.
Accidents happen, guys while being excellent hitters sometimes miss the spot, and my job is to TRY and make them which means I need to be aware. Sh#t happens and when I step out there I know what risks I am taking, we are a bit of a "crazy" breed but we enjoy the competition so we do it. It's when you have guys trying to blow you up is where the line is crossed IMO, and those guys are usually in the minority.
