Referees should be punishing dissent. I'm horrified to hear that referees aren't doing so. From a personal perspective, I hammered dissent when I was refereeing. No problem with chat and players asking questions, but there's a line in terms of how those questions are asked, and it's up to referees to let the players know where that line is and what happens when they cross it. How it affects a game shouldn't be a consideration for a referee.
