Well said, TK.
I've noticed there seem to be three groups of people: 1) the ones who hate
Disneyland Resort and everything it stands for; 2) the ones who enjoy it as just being a place to ride Space Mountain and Tower of Terror and buy a lot of Mickey Mouse merchandise; and 3) the ones who really 'get' Disneyland/California Adventure, enjoy being a kid there, enjoy the details of it, the history of it, the beauty of it - the whole immersive experience.
Those people who made the comment to Michele and her friend were probably the sorts who belong in group 2 - the ones who just see DLR as a place to ride fun rides and buy expensive merchandise. They probably don't really 'get' the whole Disney magic thing. And, while Disneyland IS that (a place to ride fun rides and buy expensive merchandise), as we all know here on the DIS, it is so, so, so much more than that, and if we can't be silly and just 'play' while at DLR, of all places, then where can we do that?
