Yes. Standing when the Bills have the ball is stupid. Sit down and be quiet pre-snap, cheer or stand up for a big play on offense, then sit and calm down again for the next play. Standing when the visitor has the ball is allowed. It's easier to scream from a standing position since the diaphragm is not restricted, so standing to make noise is fine. People who stand and don't say or do anything to make noise piss me off.
