Pageant parents put their children though crazy hell. It's also wrong to sexualize a toddler/child. But lets not forget that crazy, obsessive parents exist everywhere: football, karate, swimming, gymnastics, music, acting, etc....
The intent isn't just for the parents to relive their past successes. The parents also want their children to do something they loved. This may be an activity where the parents made friends and learned valuable lessons. They may have a lot of reasons to push their children into these activities and it's not just for one reason but ALL those reasons.
I believe that PR also wanted to groom her daughter for success. I'm guessing that she fantasized that JBR would win beauty contests, meet a very rich and educated man, and live an upperclass fantasy lifestyle better than the (odd) one she was living.
I've also just seen a lot of talk about how sinister PR was with JBR as her project. Don't get me wrong. I don't have a very high opinion of her myself. But I think that these threads tend to go overboard to paint her as a monster so it's easier to believe she committed the murder.
There are strong arguments to believe PDI. For this thread, religion doesn't fit in my mind as strongly as rage. PR arguing with her daughter, the arguments getting worse over time, JBR imposing more of that stubborn character, and PR finally lashing out. It's horrible, but then you start to panic over what you've done, how it's going to look to everyone, and you do things that get further and further away from calling an ambulance and finally lead to hiding the body in the basement. I could write that story in my sleep by now and lock a panicky motive into it with ease.
Thanks for the religion theory. I really don't understand southern religion and probably never will, but it's worth trying to understand.
And as everyone says, these are only my opinions. I guess that's a legal thang.
