Garybuss, you are spot on.
Its very difficult to be a liberal witness in the midwest even if you are a productive witness with a title (pioneer, MS, elder, CO). People watch your every move and force you to conform. If you don't conform, they are basically watching the clock and waiting for you to slip-up. LOL...They're a bunch of holy-rollers that believe all west coast witnesses are going to be destroyed.
When you leave the midwest, you find that congregations varies greatly...from 'go to college so that you can support yourself' to 'if you really love jehovah just clean the toilet and pioneer'. From "get your own place so you know whats its like to manage your own finances" to "don't leave your parents house until you get married even if you're 60 years old".
I don't think liberal JWs are more likely to leave than the militant ones. It depends when either are willing to see that there really is no Wizard but just the little men behind the curtain.
