I figure they may have been confused as to who they were messaging and the nature of this site.
In my opinion, from the outside looking in, threads of this nature will make people hesitant to join the forums or stick around; it adds creedence to the Watchtower's false description of non-believers and apostates. Being firm yet kind to people on their way out of the Jehovah's Witness cult will go a long way in getting more people to join our cause and be free of the destructive Watchtower cult of Jehovah's Witnesses.
