I am not sure if it called apostates part of the anti-christ before, but it appears they have made some changes on the page and it seems to be very strong and assertive language.
Defection
Watch Tower publications assert that members of the religion are not compelled to remain part of the congregation. [137]
However Jehovah's Witness doctrines provide no valid reason for baptised members to leave the religion. [138]
Those who do choose to depart and announce their decision to terminate their membership are described as apostates [138] [139] and part of the antichrist . [140]
Watch Tower publications direct that they are to be shunned by other Witnesses, including close relatives. [137] [139]
