Just to throw in a personal experience ... (note that I was never a Witness)
When I was a kid, I didn't do pageants -- but I did dance, baton, and modeling, which is a lot of the same stuff. Make-up, "flirty" dance moves and poses, very short and shiny skirts, hours spent on hair (I got a perm twice a year from the age of 7 until the age of 11) ... all of that stuff. It wasn't quite as obsessive as pageantry is, but my dance teacher was a pageant mom. Her little girl was a national beauty queen and actually ran in the same circle as JonBenet Ramsey.
Hours in the car to go to a fashion show ... missing the occasional school day to go be in a magazine ad ... practice sessions every day after school ... until I hit adolescence and wasn't skinny and beautiful anymore, and then it all sort of went away. I focused on school instead and, if I may say, did just fine for myself.
The end result? Actually, when I watch these documentaries about pageants, I see a lot of my childhood in them, and all I remember is how much fun it was. I LOVED doing it. I loved being on stage, I loved dancing and twirling my baton, I loved putting on make-up and getting pretty outfits and listening to the audience applaud. I think if the KID -- not just the parent -- truly loves doing it, then so be it. There has to be balance, though. I knew growing up that brains were important, that this was just a game for fun, and hey, it put some money in my college account, which I subsequently used.
The little girl who was the national beauty queen is now a very ordinary adolescent who's outgrown pageants and is instead focused on school and going to college. She seems pretty normal.
Can it be extreme? Yeah. Does it go too far? Yeah. Do some parents pursue it for the wrong reasons? Heck, yes.
Should childhood pageants, modeling, dancing, et cetera, be banned? I personally don't think so. I would compare those obsessive pageant moms to the obsessive soccer moms I see down the street, screaming about how hard their kid can kick. I could complain about the cheerleading moms and the violin moms and the theatre moms and the equestrian moms ...
All of it is about balance and making sure a kid has a hobby because THEY want it, not because their parent does.
