There's certainly no shortage of what to disagree with!
Mine would be: Lack of love, UN involvement, self-appointment of GB (the whole history of that is a travesty), lies and deceit by the GB, false prophesy, pedophelia, no questions allowed, treatment of women as lesser beings, blood transfusions, elitist attitude of GB/higher ups, work work work yet never good enough, no education, blood transfusions, hypocrisy, deliberate us of mind control. Whew - I think I could go on but that's the overall gist of my disagreements.
The havoc on people's lives is so sad! The families broken up and the lives lost is a tragedy. The elderly ones who have no pension and no savings is sickening.
