It's mind boggling that someone would spend 25 minutes debating something like this. Honestly it sounds to me like those people cared more about being right about this than they did about playing the tennis match. I can't believe how such little things can become such overblown issues. I would say people are taking this way too serious. Unless your playing in some kind of money tournament or something like that have some respect for each other and give each other the benefit of the doubt especially if it is the first time an incident came up in the match.
Also, I can't believe that players can be so distracted by someone else's grunting or doubles talk that they can't hit their own shot. Unless someone comes up behind me with a megaphone and screams into it when I don't see it coming, a little talk on the other side of the net or some grunting is not going to throw off my game. Good lord, pulling the hindrance card, no wonder people who don't play tennis think that tennis players are such pansies because a lot of them really are.
I have also noticed that a lot of the people who want to pull the rule book out on every little thing are typically the ones who create most of the problems that arise on the court. To be carrying a rule book around with you so you can argue with someone over minute issues you obviously want to win a lot more than I do. Ok my rant is over.
