During the Packers games, the white noise is not that relevant. There are a handful who (nerdmann for one) that go overboard and blame Mike McCarthy for Greg Jennings fumble, but if you are not uptight and view it more as comical, there's no problem.
I really don't understand how anyone can NOT want to be in the chat during the Packers game. If someone bothers you, /ignore. It's not like you need to read every single persons comment. Focus on the game, if you have something to say, say it. If you don't, so be it. There's commercials in the game, half time and challenge reviews.
The excuses for leaving or not being in the chat are sickening to me and it hurts my feelings and I don't think I'm going to sleep tonight.
All kidding aside, there really is no reason to not join in the chat. You don't have to watch the game, you don't have to reply to every comment, you can ignore the fools (ahem, zombieslayer and MAINLY Nonstopdrivel) who VERY RUDELY side track the discussions into something sexual. Yes, that does bother me, but during the games, they are usually behaved.
