pbrow,
There is some distance between personal belief and organised religion. You illustrated your argument with your mother's decision to shun you because of her (somewhat selfish) hope of a reward in the paradise (an unverifiable and likely false hope). Your mother's allegiance is to an organisation that keeps encouraging her to continue to shun you. If there was no such organisation, your mother would have to work out a balance between her personal belief and her natural love for you, and her natural (innate) love would likely win out over an imagined reward of life in a paradise.
Why do you think the JW organisation (as did early Christianity and similar Jewish cults of the era, like the Essenes) try to isolate members from general society? Why do you imagine the WTS discourages people from seeking tertiary studies?
There is some evidence that the WTS uses this dogma (shunning) as a means to emotionally blackmail members who may be thinking of leaving. (Many years ago an exjw who had access to the leadership clique in Australia, was told when he said he discussed leaving (by someone close to the branch committee), "Don't forget we still have your children." (These children were in their early 20s).
There is no need to prosecute anyone for personal belief, unless that personal belief impinges on someone else's rights.
