They think you need to be evil to get disfellowshiped when in reality you can get disfellowshiped quite easily for nothing serious at all.
That is so true. My elderly father. before being booted of the BoE for staying home and taking care of my dying mother, said that a person can be DF'd for anything that three men can agree on if they want you gone bad enough.
The total lack of Christian love, and the blatant nepotism that goes hand in glove with the rigid shunning is going to have a negative effect IMO.
