I'm sorry, but I sit in the Tunnel End Zone and haven't noticed this problem before. Actually, I myself get pissed off when I see a bunch of people sitting on their asses when our defense is on the field. I'm one of the types that gets up and cheers for our Defense and gets loud on all our defensive plays and if you tell me to sit down, I'll tell you to shut your mouth. If you don't like it. Stay home! We need fans who are going to be there doing there part, cheering their heads off and making noise to screw up the opponent's offense.
Now, when the offense is on the field, I sit in my seat and try to keep quiet, except for one thing...If our offense makes a big play, I will jump up and cheer the play and get excited. When our special teams is on the field, I will get up and cheer sometimes too. But the other half of the game (When our offense is on the field and timeouts), I will stay seated. Again....if you have a problem with this, STAY HOME! You can always sit on your ass and quietly watch the game at home.
My pet peeves are when people stay seated on 3rd down for our defense and/or tell me to sit down. I also can't stand when morons start the wave when our team is on offense. The wave annoys me big time, but it really annoys me when our offense is on the field. Oh and the final thing... don't cheer and get loud when Trent Edwards and the offense is on the field, especially when they are still at the line. SHUT THE !@#$ UP and wait until the play happens.
