It is not "just a bad habit." It is a "violation of a rule" that is in the Rulebook we abide by. Don't try to pick and choose which rules we want to abide by.
For instance remarks -
Rules in place to deal with all of these, except maybe #4?? Dont know what you want to do on this one?? Just need to enforce the penalties.
For the record there are many quality coaches out there who dont need a "fix" from chew. Just as there are many quality coaches who are breaking a rule by using tobacco products.
As far as the following quote -
"I chose my battles wisely, and this is not one of them. Those who have the time to go around and try to find everyone who is chewing, to try to get them kicked out obviously don't have enough on their plate during the tournaments." - clarkmom
As I said earlier. I do not go around looking for those breaking the rules, but if you come to a mat and are doing so, it will be pointed out, in the appropriate way, to an official.
