What is shaping the current thinking in a similar, life changing way?
1. Sisters should only marry worthy men, as determined by their being an MS or higher.
2. Blood transfusion bans are still taking lives of partners, children, parents.
3. Shunning is stopping children having a relationship with their families.
In another 25 years time when these restrictions are laughed at for being old light, there will be old, single sisters who passed up opportunities for happiness, distraught ones who needlessly lost those close to them, and ageing parents who have no children or grand children to care for them because they were cut off decades ago.
Yet the GB will be fine, and it will be 'the witnesses' who read too much into things.
