You're the one who was all for supporting the hipcheck

Look I've never been anywhere in Disney that I felt like creating some sort of physical blockade was necessary - whether by elbows out, knees up, holding hands or whatever. My family has no need to police Disney queues in any situation. If we have a problem we take it to a CM. Hearing the cheers of a crowd behind for blocking a couple of Brazilian teens on Soarin' (as so many folks brag about on these boards) really wouldn't do anything for my ego or make my day go any smoother.
But that's just me and my family. Had that guy at Pooh last year (when the CM asked us to move up as a party of 2) actually touched or hipchecked or elbowed me or my son - THINKING he was blocking a line jumper - it would not only have been addressed with Disney, but with the Orange County PD. He wasn't paying attention to the CM and just thought we were trying to cut. He physicall stuck his arms out and put his hand in my face. With a nasty voice said "NO - keep your party together!" He put his arms back on the wall and railings and stood there snarling at me and DS6 (at the time). I finally had to call out to the CM who then explained to the guy that we had been asked to come forward.
Now I realize that is a different circumstance than someone who actually does just cut in line, but the to me it doesn't really matter. No one has the right to intimdate another person with implied force. People at Disney do stupid stuff, they don't know what the general procedures are, they're excited, they make stupid mistakes. Most people aren't out to get anybody. The occasional jerk will or group of people, but most people aren't out to get other people at Disney.
Feeling threatened by someone in line at Pooh is simply not acceptable. I'm sure he was quite proud thinking he was going to block some mom and her little boy from cutting in line - all he did was ruin my morning with the whole encounter.
So no - I just don't get it. If I felt like I had to make a human chain with my kids to keep people from getting in front of us - I wouldn't be at that attraction.
