BANE The Watchtower Society considers members that leave their organization to be apostates. But that is their interpretation of an apostate. An apostatize is someone who abandons their faith.
To apostatize from Christianity one would have to turn away from the teachings of Christ. Many here have not turned away from the teachings of Christ but from the changing teachings of the Watchtower Society. They defend their faith in Jesus at great length on this forum.
The founders of your organization, including Russell himself apostatised. Most of Jehovah's witnesses apostatized to join your club. So by definition your organization is an apostate organization made up of people who were disillusioned with their previous religion.
Your members called at their door and encouraged them to be unsatisfied with their religion and apostatize. 'Religion is snare and a racket.' Remember? Having been sucked in with false promises, is it any wonder they moved on when they found out that your society was no more honest that the religions they previously left?
