Once you understand that the GB/FDS are just men and not directed/inspired the whole house of cards comes crashing down.
The fact their self appointment in 1919 is based on 1914, 2520 years from 607 BC and that date is easily disproved as wrong for the destruction of Jerusalem then its quite easy to cause the house of cards to come down for others if they research 586/607.
You can't go back after you know the truth about all of that.
