The easy solution is mark the upper sections as "casual" sections, and the lower sections as "active" sections. If you don't like standing, yelling, or get angry that someone drops the A-word (@$$) within 4 rows of your precious little girl teenager (who says that all day at school anyway), then move to the top section.
This is pretty much how it is, without the labels. It's like at a major league baseball game. If you want to be obnoxious and stand the whole game, you know to sit in the bleachers. I think this will sort itself out over time at SMU games as our fan base grows and solidifies.
At SMU games, if you're going to stand the whole game and make noise beyond reacting to big plays, go sit over on the student side. You will be happier and the people on the pressbox side will be happier. It's just that easy. There's a place for everyone at a college game -- and plenty of room. Not everyone should have to follow the same decorum. Your right to stand and scream nonstop for four hours is the same right as the person who wants to have a pleasant gamewatching experience.
It takes a lot for some people to stand up, or to stand for long stretches. When I was in my 20s, no problem. Now, with bad knees and a sore back, I'm not so quick to jump up anymore. I like the fact I can sit during a game. Fortunately with the new videoboard, I can still watch plays when people jump up in front of me, but that isn't always the case.
Part of the problem, too, is all the lulls in action at a college football game. The endless media timeouts, commercials on the video board, etc. It's not like there's non-stop action and energy. I stand up and cheer when it will help the team. If I'm standing and screaming or blowing a horn during a timeout or other lull in the action, then I'm really only entertaining myself. That's fine if you're near the student section, where obnoxious behavior should be a requirement for all college age people.
I have no problem with kids being kids, or even older people acting like kids, as long as they're in the kids' section. Same goes for the blue hairs - stay out of the student section, you old goats!
