Watchtower's ignorance around the historical background to many Biblical directives has had a very negative effect on the lives of Witnesses.
For instance Paul said women should cover their heads because in Corinth prostitutes walked the streets plying for business with their heads uncovered.
Hence head coverings were never a symbol of headship but a directive very specific to that period, as was the BLOOD DIRECTIVE!!
Watchtower leaders have been lawyers, businessmen, civil servants and door-to-door book salesmen, never, ever historians or Biblical scholars. And it shows!
