You obviously never played the game of baseball. Brushback pitches to control the inside part of the plate are fine. Throwing at a guys head is definitely off limits. Pedro showed he was a classless act. Pointing to his head and threatening to hit someone in the head? Come on, even a Red Sox fan can't condone that. You're messing with a guy's career and his health. Even if you want to hit a guy, the unwritten rule is to keep it from the waist on down.
