This.
I feel like those people who feel the need to judge, scold and basically make other vacationers feel uncomfortable are acting more childish than the person who thinks it's ok to cut. Again--- you have NO idea what the situation or reason behind a separated group might be. Give people the benefit of the doubt, I say. Be the bigger, better person and let it go.
And really... how often does it happen when you stand in line? Every line? Same person every time? Doubtful.
I like the PP thought on Karma. While I don't believe in Karma exactly, I do think the universe has a way of righting itself. They aren't winning any prize by acting like jerks if they are just cutting for the sake of cutting. But neither are we who feel the need to treat them poorly for the same action.
Extremely well said. The person you're hurting most when you allow yourself to get upset about things outside your control (e.g. other people's actions) is really yourself. Even if you would manage to "chasten" or even stop the person you deemed to be "line cutting," you're likely the one carrying that anger, upset and adrenaline around, which inevitably taints your vacation.
And I say that non-judgementally, because it's something I struggle with, too. One quick Disney example: I was standing in line to leave the park one cold and very crowded night and a large family with two strollers AND a wheelchair literally shoved me out of the way, separating me from my then-three-year old, to get ahead of me. I got very upset because my son was out of the park, ALONE, without me and I could no longer see him. These people laughed at me when I said they cut me off and my son was out there and wouldn't let me go ahead, saying something not very nice at all that I recall included a few four-letter words (in their defense I was pretty panicked and yelling too, about needing to get to my son, though I know I didn't curse because that's not my style). I was frantic and very upset. All ended well, as I ran from exit to exit and finally got out to find my son crying, and a little scared, but with a cast member. The person who was upset in that situation, wasn't the family who cut me off and then denied it, it was me, and that anger/fear emotional rush lasted long after the incident.
I have three times, in three Disney visits, had to get out of line with my son, aged 3 and 4 at the time, where we eventually rejoined my husband and/or others in our party in line. Some here would say my reasons (child's meltdown, potty break and cut foot, respectively) were justified, others wouldn't. I did try to do it as nicely as possible--waiting until we had to pass the least amount of people possible--and explain and apologize to all the people we directly walked by what had occurred. Everyone was very nice, for which I was grateful, because I'm the kind of person that if I'd run into someone "throwing elbows" or "telling me off," as others describe here (some proudly), would have ended up leaving Disney that day in tears.
Like I did the day my just-turned four-year-old had an accident in line at Innoventions ... For the very reason (he later told me) that it was just he and I that day and the last time he'd told me he had to go, we got out of line and had to start all over again. That day, people (cast members and fellow guests alike) weren't very nice, or understanding, at all, about the situation. (And, no, I didn't try to get back in line, I mean just helping me get out of the tight line, get the mess cleaned up--which did not happen quietly, as I'd hoped--and find a restroom to get him cleaned up and calmed down). We both ended up leaving the park very unhappy and embarrassed, and I had some mommy anger that a little more consideration wasn't given for a clearly upset and embarrassed child.
I've also been in a Disney line situation where my mother-in-law was drinking coffee while we waited in line, and the attendant said she couldn't take it inside once the line reached the ride's interior (there was an inside and outside portion of the queue), so we stood there and allowed people to pass while she finished, and then went in when she was done. Still, even though we'd stood in the entire line, and even let probably 30-50 people pass us by (telling them why as we did), the group of people we eventually went in before kept talking about how we "cut" in line in front of them, which definitely effected me and made me feel awful. (So, in their mind, mission accomplished.) I'm sure some on the Dis would argue we should have gotten out of line and started all over, but I, personally, don't think we did anything even slightly wrong.
Even at the age of 2 my son stood in line. We kept him entertained with snacks and little toys that I'd have in my bag. If we could do that, so can everyone else. If kids are running around, pulling on the ropes, screaming (and don't have a disability) that's more of a parenting issue then anything else. Sorry, but that's how I see it. If a kid really wants to ride something, they'll behave. If not then no one rides. That's how I see it.
I really hope I never have the pleasure of bumping into some people at DL. 
hug it out man, hug. it. out!
