No way in hell. If it were up to me, if the game was intense, I would stand the entire game. It wasn't me, but Fan A might as well be me.
No fan at a game is going to tell me how to cheer my team on, especially if I was not initially disrespectful. If you don't like it when I stand, stand yourself. The stadiums do have "stadium style" seating so that you could see, if you would just stand.
The bigger question is why would would "shell out a chunk of cash" for those good seats, and just sit there. There is a reason why they have motivators at games, ITS TO PUMP UP THE CROWD AND ADD EMOTION!!! I would enjoy the experience the game that much more, if the people that sat immediately around me, were as passionate for the game as I am.
The same thing is happening at Cardinals games, (although it is more rare)
I would rather be around passionate Cowboy and Laker fans, than docile Suns fans.
