"Only paying attention to some parts of the show? Maybe you’re right: I obviously slept through the scenes in which the folk of Indiana were characterized in any kind of detail. I only imagined the girl’s song that was framed as a denunciation of Indiana, as well as the production number in which Christopher Sieber made all of the kids look like idiots. The homophobic mom was a fully rounded character, with her own song and everything. Sorry: this rube missed it all from the fourth row center.
All of the material you cite is, in fact, in the show -- and so is all of the other, balancing material that you have chosen to ignore as if it isn't there. That's exactly my point.
P.S. Christopher Sieber's character made all of the kids look like idiots to the extent that people who think they can cherry-pick certain strictures of the Bible to pay attention to and condemn others for violating, while ignoring other parts (because they themselves are guilty of those "sins"), are idiots.
