Further, talk to your Christian parents and the congregation elders about your desire
Here they are telling young ones not to talk to their non-christian parents. How much respect is that showing for them? You realize they have gone way off track when they are not teaching good bible morals, there is no stipulation in the bible when it advises to 'honor your mother and father'. Regardless of whether a child's parent is a JW or not, most still have their children's best interest at heart and can provide sensible advice, no doubt a reason why they wouldn't want them talking to them.
As a non-christian parent I can't agree more. I caught this too. They know that a non-christian parent would stop this in a second, or at least provide some RATIONAL pros and cons to doing this type of thing. A non-believer is basically nothing to them. Plus, going abroad can be a great experience for a young person. But not necessarily doing it this way. I can tell you right now that (especially thanks to websites like this) I will be doing everything I can to make sure she knows ALL of her alternatives in life after high school.
