We were at a Christmas party. We were standing in a spot in the midst of the crowd. Then many people began to sit down around us, but I am a big, old woman and I simply cannot sit on the ground. It is physically impossible for me to do so. So, I remained standing. People around starting chanting "SIT DOWN" to us and a few other old people that were similarly stuck but also couldn't sit down. Most people around me responded by sitting down. One poor little old lady stood nearby me leaning on her cane and crying. Her daughter tried to make her sit down, but I told her to leave her alone and let her stand. the crowd was trying to collectively shame us into doing something that, if possible for some, would be at best painful and at worst dangerous. If I could have gotten out of there I would have happily left, but it was dark and crowded and I am not agile enough to safely navigate through all those seated people. It was one of the saddest experiences that I have ever had in WDW. I didn't know what else to do but wait it out - it was actually very scary. I never go to watch these events anymore because I would never risk getting stuck in a similar situation. I watch the high fireworks from our hotel across the way.
You do not have the right to tell other people what they have to do because you want them to do it. You can ask, but they have the right to refuse. It may seem rude to you, but you don't know why they are standing there. Perhaps if you did, you would understand and feel a bit badly about your own attitude. I am surprised by many suggestions of equally reprehensible behaviour in retaliation. Does reacting in a rude way to another person help the situation? Who is the winner there?
It isn't worth the cost.
I agree that Disney needs to make rules regarding sitting and standing and make people aware of them at the outset. Then CM's, not the crowd, should enforce the rules.
