LV101 - You're right, it is tough after being raised in the Watchtower to argue that they should be able to have protection of the law. It's tough to see people being misled and misinformed, making unwise decisions, and suffering for it. Too many are indeed misled by the petting panda paradise.. lol.
I'm involved with a program where I work with high school students (I'm not a full-time teacher), and I involved the class in a discussion on whether the government should protect people from their own religion, since it related to part of the curriculum. We used the example of the Amish. Now, the Amish are generally looked at as "cute" and "quaint" by society, unlike JWs, probably because they don't proselytize and they sell delicious baked goods. But some have argued that the government should step in. They do practice shunning for baptized members who leave, and in many orders they do not seek proper medical care - not only blood, but also other important care. Generally they get about an 8th grade education in Amish schools, which does not prepare them well for life outside if they decide to leave. Also, unlike JWs, young Amish do not have the ability to explore criticism of their doctrine, as they do not have access to the internet, television, or even radio. Really, despite the generally favorable public opinion, I think if JWs were to be classified as a cult by the government, it would be very hard to argue that the Amish are not also a cult.
In any event, we discussed the idea of whether the government should be able to require the Amish children to get a normal education up to age 18, as most states require for the general population. (Currently the Amish do not have to meet this requirement even if the state requires it in general). This way, children would be more prepared for life outside if they decided to leave, and also would be more prepared to think critically in evaluating their doctrines and choices in life. Almost the entire class believed that the government should stay out. I think this is probably representative of the prevailing attitude in the US; we tend not to see it as the government's job to paternalistically protect citizens from believing something not in their best interests.
